Two cocoa types are predominantly being cultivated in Ecuador, the highly appreciated fine Nacional and the high-yielding and disease-resistant CCN51, classified as bulk. With the introduction of foreign germplasm in Ecuador and the international demand for high-quality Nacional cocoa, the present study aims to characterize and compare the flavor profile of Nacional hybrids (EET103, EET559, EET576 and EET577) and CCN51, and to assess the effect of the genotype. The fermented dried beans were processed into liquor and their sensory properties, volatile composition and odor fingerprint were analyzed by trained panelists, headspace-solid phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS), and GC electronic nose (e-nose), respectively, combined with multivariate statistics. Seventy volatiles were identified and semi-quantified, among them, 16 and 14 volatiles conferring fruity and floral aroma notes, respectively. CCN51 was mainly characterized by undesirable odor-active volatiles, whereas the EET cultivars contained the highest concentration of most fruity and floral volatiles, with differences in between EET cultivars. Sensory data highlighted organoleptic differences between the fine and bulk liquors, i.e. the fruity and acid EET flavor strongly differed from the bitter, astringent and off-flavor attributes of CCN51. Principal component analysis (PCA) discriminated firstly between fine and bulk, and secondly between EET identity. Partial least squares analysis identified possible correlations between sensory attributes and volatile compounds. Besides, e-nose proved its usefulness for rapid assessment of the liquors’ sensory profile. The results provide a foundation for understanding the genotype’s contribution to and the compositional basis of Ecuadorian fine and bulk cocoa flavor.

The B3NO2 six-membered heterocycle (1,3-dioxa-5-aza-2,4,6-triborinane = DATB), comprising three different non-carbon period 2 elements, has been recently demonstrated to be a powerful catalyst for dehydrative condensation of carboxylic acids and amines. The tedious synthesis of DATB, however, has significantly diminished its utility as a catalyst, and thus the inherent chemical properties of the ring system have remained virtually unexplored. Here, a general and facile synthetic strategy that harnesses a pyrimidine-containing scaffold for the reliable installation of boron atoms is disclosed, giving rise to a series of Pym-DATBs from inexpensive materials in a modular fashion. The identification of a soluble Pym-DATB derivative allowed for the investigation of the dynamic nature of the B3NO2 ring system, revealing differential ring-closing and -opening behaviors depending on the medium. Readily accessible Pym-DATBs proved their utility as efficient catalysts for dehydrative amidation with broad substrate scope and functional-group tolerance, offering a general and practical catalytic alternative to reagent-driven amidation.

Two tetradentate (NNOP) ruthenium products [{RO-C5H3N-C5H3N-CH(O)-C6H4-PPh2}Ru(CO)(PPh3)]Cl (1: R = Me; 3: R = Ph) were isolated by the reactions of the corresponding ligands with RuHCl(PPh3)(3)(CO). Complex 1 could also be transformed into 2 when heated in THF, through C-OMe bond cleavage. The mechanism of the unusual C-O cleavage in complex 1 was investigated, and the results indicate that it is an S(N)2 mechanism through the attack of trace amounts of neutral H2O. In contrast, in the presence of KOH, the reaction switches to an SNAr chemistry. The bidentate ruthenium isomers [{CH3O-C5H3N-C5H4N}RuH(CO)(PPh3)(2)]Cl (4a and 4b) could undergo similar C-O cleavage, affording product {O-C5H3N-C5H4N}RuH(CO)(PPh3)(2) (5), which reacted with HCl to generate complex [{HO-C5H3N-C5H4N}RuH(CO)(PPh3)(2)]Cl (6). These complexes were tested as catalysts for beta-alkylation of secondary alcohols with primary alcohols, and a series of beta-alkylated 1-phenylethanol derivatives were isolated in high yields.

Ru(III)/dimaval was deposited on chitosan aerogel through the ionic interactions of the proton exchange between the dimaval sulfonic acid and chitosan aerogel amine group. After characterization, the composite was used in the oxidation reaction of certain alkylarenes, aliphatic and benzylic alcohols as well as cyclohexanol. High conversions and excellent selectivities were obtained for the solvent-free reactions using a low catalyst amount under aerobic conditions at 80 degrees C for 2-5 h. The organometallic compound is applicable as a heterogeneous catalyst having high chemical stability and recyclability up to eight times. [GRAPHICS] .

Gold catalysts are best known for their selectivity in oxidation reactions, however, there is a promising future for gold in selective hydrogenations. Herein, the hydrogenation of several aldehydes and important bio-based chemical building blocks, namely 5-hydroxymethylfurfural (5-HMF), furfural and vanillin, was performed throughout the combination of Au nanoparticles with Lewis bases. The Au-amine ligand (e.g.. 2,4,6-trimethylpyridine) catalytic system could reduce the aldehyde carbonyl group selectively, without reducing alkene moieties or opening the furanic ring that occur on most traditional catalysts. Otherwise, the reduction of nitro group is preferential and the catalytic system was used for the synthesis of furfurylamines, important intermediates in the synthesis of different pharmaceuticals (e.g., furosemide), through the selective reductive amination of furfural starting from nitro-compounds. Moreover, a fully heterogeneous gold catalyst embedded in N-doped carbon (Au@N-doped carbon/TiO2) was able to perform these reactions in successive recycles without the addition of ligands, with impact in the development of a continuous flow process for biomass valorization.

A novel array double dielectric barrier discharge (ADDBD) combined with a TiO2/Al2O3-Co3O4/AC (Ti-Co) catalyst was applied to remove toluene. The effects of catalyst setting distance, catalyst combination mode, and process factors (including specific input energy, initial toluene concentration, and relative humidity) were investigated in terms of the toluene degradation efficiency (eta(t)(oluene)) and the selectivity of CO2 (S-CO2). When the specific input energy was 65 J.L-1, the initial toluene concentration was 100 mg . m(-3), and the relative humidity was 30%, the highest eta(t)(oluene) of 72% and Scot of 44% could be achieved with TiO2/Al2O3 10 cm and Co3O4/AC 20 cm downstream of the ADDBD. Based on the determination of active substances (e.g., O-3, center dot OH) and the catalyst activation mode, a synergistic effect of active substances and photon between the ADDBD and the Ti-Co catalyst was proposed for the removal of toluene. Finally, the biodegradability and toxicity of the outlet gas were evaluated, and the results showed that the outlet gas was more convenient for subsequent biopurification and less toxic to the surroundings after the treatment by the ADDBD combined with the Ti-Co catalyst.

A three-component domino reaction for the synthesis of naphtho[2,3-b][1,6]naphthyridine derivatives has been established. Such strategy exhibited excellent substrate scope including various enaminones and aldehydes that afforded a series of multifunctionalized naphtho[2,3-b][1,6]naphthyridine derivatives with 70-86% yields. The advantages of bond-forming efficiency, accessibility of starting materials, and water as sole byproducts provide invaluable access to biological 1,6-naphthyridines.

Alkylidene carbenes undergo rapid inter- and intramolecular reactions and rearrangements, including 1,2-migrations of beta-substituents to generate alkynes. Their propensity for substituent migration exerts profound influence over the broader utility of allcylidene carbene intermediates, yet prior efforts to categorize 1,2-migratory aptitude in these elusive species have been hampered by disparate modes of carbene generation, ultrashort carbene lifetimes, mechanistic ambiguities, and the need to individually prepare a series of C-13-labeled precursors. Herein we report on the rearrangement of C-13-alkylidene carbenes generated in situ by the homologation of carbonyl compounds with [C-13]-Li-TMS-diazomethane, an approach that obviates the need for isotopically labeled substrates and has expedited a systematic investigation (C-13{H-1} NMR, DLPNO-CCSD(T)) of migratory aptitudes in an unprecedented range of more than 30 alkylidene carbenes. Hammett analyses of the reactions of 26 differentially substituted benzophenones reveal several counterintuitive features of 1,2-migration in alkylidene carbenes that may prove of utility in the study and synthetic application of unsaturated carbenes more generally.

Old World (Africa) and New World (South America) arenaviruses are associated with human hemorrhagic fevers. Efforts to develop small molecule therapeutics have yielded several chemical series including the 4-acyl-1,6-dialkylpiperazin-2-ones. Herein, we describe an extensive exploration of this chemotype. In initial Phase I studies, R-1 and R-4 scanning libraries were assayed to identify potent substituents against Old World (Lassa) virus. In subsequent Phase II studies, R-6 substituents and iterative R-1, R-4 and R-6 substituent combinations were evaluated to obtain compounds with improved Lassa and New World (Machupo, Junin, and Tacaribe) arenavirus inhibitory activity, in vitro human liver microsome metabolic stability and aqueous solubility.

The first highly enantioselective intermolecular Stetter reaction using simple enones is reported. A series of novel chiral BAC structures were designed and prepared. They were tested in the Stetter reaction with simple aldehydes and enones. The products were generated in excellent yields and enantioselectivities (up to 94% ee). Surprisingly, a substoichiometric amount of water was crucial to obtain high enantioselectivities. Chiral BACs were also shown to catalyze 1,6-conjugate addition reactions with paraquinone methides enantioselectively.
