An ‘on-water’ protocol has been developed for the synthesis of combretastatin A-4 (CA-4) analogues by cyclization of polarized triaryldivinyl ketones using hydrochloric acid as a promoter in 45-95% yields. The reaction time was reduced by about 30 times due to ultrasonic irradiation at ambient temperature. The other advantages of this new method are operational simplicity, easy workup, no column purification, and applicability on a gram-scale. It was shown that the amphiphilicity of the substrate and a low energy barrier of the reaction are a prerequisite for electrophilic and concerted reactions under aqueous and ambient conditions.

Oxidation of benzylic position in alkylphenols with molecular oxygen in acidic conditions, which is very difficult because of the intense dimerization or polymerization, was investigated with various combinations of noble metal catalysts. The combination of Pt/C and Pd(CH3COO)(2) catalysts showed activity in the formation of p-hydroxybenzaldehyde formation from p-cresol. The best p-hydroxybenzaldehyde yield was 35%, which was obtained in 50 wt% aqueous acetic acid, Pt on carbon : Pd(CH3COO)(2) weight ratio = 1 : 2, at 353 K. From XRD, TEM-EDX and XAFS characterizations, the Pt and Pd species were totally reduced to Pt and Pd metal particles, respectively, in spite of the oxidative reaction conditions. Polymerized products (tar) of p-cresol formed with Pt/C catalyst and air can be the reductants for Pd(CH3COO)(2) into Pd metal. The catalysts or catalyst combinations without Pd degrees metal showed no activity in the formation of p-hydroxybenzaldehyde, suggesting that Pd is the active species. The effects of the air pressure and presence of radical scavenger were very small, suggesting that non-free-radical mechanism was involved.

Chiral acetylenic derivatives are found in many bioactive compounds and are versatile functional groups in organic chemistry. Here, we describe an enantioselective nickel/Lewis acid-catalyzed asymmetric propargylic substitution reaction from simple achiral materials under mild condition. The introduction of a Lewis acid cocatalyst is crucial to the efficiency of the transformation. Notably, we investigate this asymmetric propargylic substitution reaction for the development of a range of structurally diverse natural products. The power of this strategy is highlighted by the collective synthesis of seven biologically active compounds: (-)-Thiohexital, (+)-Thiopental, (+)-Pentobarbital, (-)-AMG 837, (+)-Phenoxanol, (+)-Citralis, and (-)-Citralis Nitrile.

The covalent functionalization of 2D transition metal dichalcogenides (TMDCs) with organic molecules exploiting the thiol conjugation approach is still a very controversial topic. We have synthesized thiolated tetraphenyl porphyrins, with and without hydroxyl groups in the phenyl substituents, which have been covalently attached to chemically exfoliated MoSe2 (ce-MoSe2) nanosheets. XPS and FTIR have revealed the formation of sulfo-selenide bridges, specifically on the edges of the ce-MoSe2, as confirmed by first principles calculations. The electrocatalytic activity of TMDCs in the hydrogen evolution reaction (HER) has been investigated after conjugation with the organic molecules. The HER activity is suppressed or enhanced according to the presence of mildly acidic hydroxyl groups in the attached molecules, since they provide a local proton relay boosting the production of H-2, especially under mildly acidic conditions (pH = 4.3). Moreover, the well-known light-harvesting properties of porphyrins have been exploited to improve significantly the light-assisted HER activity. Due to the formation of a type II heterojunction or Schottky contact between the molecules and the 2H and 1T MoSe2 nanosheets respectively, the hybrid materials show an improvement of the HER onset potential under illumination compared to the pristine material, without activity loss for more than 16 h.

A general asymmetric deconstructive alkynylation of cyclic oximes with terminal alkynes was reported using copper/chiral cinchona alkaloid-based N,N,P-ligand catalysts and used to produce more than 60 examples of enantioenriched gamma- and delta-alkynyl nitriles in a highly functional group-compatible manner. A wide variety of low-cost terminal alkynes and easily available cyclic oximes with substituent diversity were found to be well tolerated with the current asymmetric transformation with good functional group tolerance. The resulting chiral alkynyl nitriles are intermediates, which could be converted into skeletally diverse chiral molecules, including delta-alkynyl amides, epsilon-alkenyl carbamate, and zeta-keto nitrile, under suitable reaction conditions.

To evaluate the inhibition of by-products that exist in pretreated lignocellulose hydrolysate on bioethanol fermentation, quantitative structure-activity relationship (QSAR) models were established in the present study. These models have the potential to predict the fermentation inhibition to minimize the experimental effort. They also provided an innovative methodology for removing fermentation inhibitors purposefully and for optimizing pretreatment parameters and thus could enhance the bioethanol yield. The results indicated that the fermentation inhibition of phenolic aldehyde were stronger than that of phenolic acid followed by phenolic alcohol in which the fermentation inhibition was weakened by the existence of the methoxy group in the benzene ring. Meanwhile, the formation of the intramolecular hydrogen bonds of fermentation inhibitors also played an important role in weakening their fermentation inhibition. The individual fermentation inhibition of fermentation inhibitors was found strongly related to their molecular descriptors. Furthermore, ferulic acid was chosen as the representative inhibitor for the primary investigation on the combined fermentation inhibition of the various complex binary fermentation inhibitor mixtures, which co-existed in the lignocellulose hydrolysate. As indicated by the results, antagonism occurred mainly under the higher ferulic acid concentrations in the binary mixtures, while a simple additive effect was generated.

A large library of thioether/selenoether-phosphite ligands have been tested in the Pd-catalyzed asymmetric allylic substitution reaction. The presented ligands are derived from cheap and available carbohydrates and they are air-stable solids and easy to handle. Their highly modular nature has made it possible to achieve excellent enantioselectivities in the substitution of a range of hindered and unhindered substrates (ees up to 99% and 91%, respectively). In addition, twelve C-, N- and O-nucleophiles can be efficiently introduced, independently of their nature. Among the whole library, ligands that contain an additional chiral centre in the alkyl backbone chain next to the phosphite group and an enantiopure biaryl phosphite group provided the best enantioselectivities. In general, there is a cooperative effect between these two chiral elements, and therefore, a matched combination between them is necessary to achieve the highest enantioselectivities. However, in the case of cyclic substrates, this cooperative effect is less pronounced and advantageously, both enantiomers of the product can be obtained by setting up the desired configuration of the biaryl phosphite group. Studies of the key Pd-pi-allyl intermediates allowed us to better understand the enantioselectivities obtained experimentally.

Carbon-supported palladium catalysts are widely used for hydrogenation of various organic compounds in the fine chemical industry. The nanoscale geometry and electronic structure of supported Pd nanoparticles play a crucial role in providing the necessary catalytic properties. To improve catalytic activity and selectivity of Pd nanoparticles, it is possible to fine tune their intrinsic properties (e.g., size and oxidation state) by controlling the chemical transformations at different stages of catalyst preparation. Recent years have seen considerable advancement in developing new catalyst preparation techniques as well as in understanding the mechanism of active site formation. This review summarizes some of the existing approaches to regulating the catalytic properties of carbon-supported palladium by variation of the carbon support, the composition of palladium precursor and its reduction conditions, as well as the addition of a second active metal. The data presented may be useful for researchers developing efficient Pd/C catalysts for hydrogenation of polyfunctional organic compounds.

We describe an efficient, clean and metal-free procedure for the synthesis of amides via oxidative amidation of aldehydes with anilines using graphene oxide (GO) as a recyclable catalyst and KBrO3 as a mild oxidant in aqueous medium under microwave irradiation. GO nanosheets were prepared and characterized by XRD, TEM, SEM, and FT-IR, analyses. GO showed high compatibility with KBrO3 in water and offered high TOF value (1.30 x 10(-3) mol g(-1) min(-1)). GO oxygen functionalities catalyze the oxidative amidation effectively in mild condition with high recyclability. A plausible mechanism was proposed by the isolating the intermediate.
