We have recently reported a one-pot procedure for glycosyl amides synthesis using selenocarboxylate as traceless reagent. Herein, we present a further application of selenocarboxylate-azide reaction for amide bond formation on a broader range of substrates, including heterocyclic systems and fatty acid. This method proved to be highly efficient for the synthesis of primary and secondary amides, sulfonamides, imides, phosphoramide and also carbamate. (C) 2020 Elsevier Ltd. All rights reserved.

The combination of nucleophilic nitrenoids and pacid catalysis has emerged as a powerful tool in heterocycle synthesis. Accessing more varied heterocycle-substitution patterns by maintaining the same reaction pathways across different alkynes remains a challenge. Here we show that Au(I) catalysis of isoxazole-based nitrenoids with alkynyl thioethers provides controlled access to (3 + 2) annulation by a regioselective addition beta to the sulfenyl group. The reaction with isoxazole-containing nitrenoids delivers sulfenylated pyrroles and indoles as single regioisomers bearing useful functional groups and structural variety.

Chiral tertiary alcohols are important building blocks for the synthesis of pharmaceutical agents and biologically active natural products. The addition of carbon nucleophiles to ketones is the most common approach to tertiary alcohol synthesis but traditionally relies on stoichiometric organometallic reagents that are difficult to prepare, sensitive, and uneconomical. We describe a mild and efficient method for the copper-catalyzed allylation of ketones using widely available 1,3-dienes as allylmetal surrogates. Homoallylic alcohols bearing a wide range of functional groups are obtained in high yield and with good regio-, diastereo-, and enantioselectivity. Mechanistic investigations using density functional theory (DFT) implicate the in situ formation of a rapidly equilibrating mixture of isomeric copper(I) allyl complexes, from which the Curtin-Hammett kinetics determine major isomer of the product. A stereochemical model is provided to explain the high diastereo-enantioselectivity of this process. Finally, this method was applied to the preparation of an important drug, (R)-procyclidine, and a key intermediate in the synthesis of several pharmaceuticals.

Herein, we report a Ni-catalyzed reductive coupling for the synthesis of benzonitriles from aryl (pseudo)halides and an electrophilic cyanating reagent, 2-methyl-2-phenyl malononitrile (MPMN). MPMN is a bench-stable, carbon-bound electrophilic CN reagent that does not release cyanide under the reaction conditions. A variety of medicinally relevant benzonitriles can be made in good yields. Addition of NaBr to the reaction mixture allows for the use of more challenging aryl electrophiles such as aryl chlorides, tosylates, and triflates. Mechanistic investigations suggest that NaBr plays a role in facilitating oxidative addition with these substrates.

Lignin holds the potential to obtain key monoaromatic compounds upon its depolymerization. Depolymerization of woody biomass by pyrolysis is well established but often unsuccessful for lignin due to a combination of its melting, agglomeration, and modest yields towards aromatics. Therefore, several lignin additives have been put forth to overcome one or more of these hurdles. Although some seem promising, a direct comparison is obscured by differences in applied technical lignin types, reactor configurations/scales, and product analyses. Moreover, the effects of additives have either been evaluated mostly on an analytical scale or their mode of action is not entirely understood. This work involves the addition of clays, calcium hydroxide and sodium formate to lignin, each having a different (putative) mode of action, in a well-defined and comparable manner. Organosolv lignin and lignin with additives were analysed by TGA/DSC and py-GC/MS. Pyrolysis was performed in a lab-scale reactor (350 g feeding). The pyrolysis liquids were characterised through elemental analysis, GCxGC-FID, GCxGC-HR-ToF-MS, GPC, and HSQC NMR analyses. All additives overcame melting issues and led to increased liquid yields but the most promising were attapulgite and calcium hydroxide. Lignin with attapulgite resulted in a heavy phase with the highest carbon yield (25.7%) and a substantial monomer yield (18.9%, mostly alkylphenols). Lignin with calcium hydroxide resulted in a heavy phase with the highest monomer yield (23.8%, mostly alkylphenols) at a substantial carbon yield (15.1%). The pyrolysis mechanisms for lignins with additives are elaborated and updated in this work.

The Beckmann rearrangement is a versatile method for the preparation of secondary amides from ketones via oxime intermediates and has been widely used in the synthesis of bioactive natural products and pharmaceuticals. Herein, we have developed a highly efficient direct method for the preparation of secondary amides and lactams from ketones using O-(mesitylsulfonyl)hydroxylamine (MSH). The reactions proceed rapidly at room temperature under mild condition without requiring any additive, and tolerate multiple functional groups. A simple aqueous work-up often furnished the products in excellent yield with high purity. (C) 2020 Elsevier Ltd. All rights reserved.

A new approach to functionalize porphyrinoids was developed based on the Vilsmeier formylation followed by the azine formation and a new class of the compounds namely azines of porphyrinoids was obtained. Variously substituted azine porphyrins, chlorins and their dyads were synthesized, and their structural and electronic parameters were studied with X-ray diffraction analysis, electronic absorption and emission spectra, electrochemistry and DFT calculations. Azine represents a very peculiar bridge with an unclear conjugation ability affecting optical properties of chromophores. This work was aimed to reveal azine properties and the influence of the azine bridge on the chromophores linked. The results of investigation allowed to conclude that azine bridge can partly be regarded as a conjugation switch with a high threshold level of switching, where limited conjugation in the ground state can be greatly increased at higher energy states of the azine molecule.
