The objective of this work is to apply yellow mustard seeds in the enzymatic reduction (biocatalysis) of acetophenone and its derivatives, providing a new biocatalyst for this type of reduction. The reaction parameters were optimized from acetophenone, resulting in 1-phenylethanol, with 68.5% conversion yield and 53% enantiomeric excess (e.e.), analyzed by GC and HPLC, respectively. Reactions to acetophenone and its derivatives were conducted in aqueous medium using buffers pH 6.0 and pH 6.5 in the presence of PVP. A polymer that can act as a protector preventing oxidation of peroxidase enzymes. The results for the derivatives presented low yields (4-18%: substances 5, 7 and 8), moderate (28-40%: substances 3, 4 and 6) and optimum (81%: substance 2) yields, with enantiomeric excesses varying from good to excellent results. Meta-substituted derivatives showed inversion of configuration in the presence of PVP. The biocatalyst was also tested in reactions with other carbonyl compounds, presenting moderate results. In this way, this work offers a new perspective of the application of PVP in biocatalysis reactions and a new biocatalyst for future applications.

Celecoxib containing pyrazole derivatives were synthesized by path aldol condensation of substituted ketone with trifluoroethyl acetate subsequently by cyclization of the formed chalcones with 4-methanesulfonylphenylhydrazine. Here, a one-pot synthesis of celecoxib and substituted analogues have been reported which are nonsteroidal anti-inflammatory drugs for their cyclooxygenase (COX) inhibition, anti-inflammatory activity and ulcerogenic liability. In order to intermediate work-up, a continuous one-pot synthesis has been developed, performing the entire reaction sequence that results in a shorter time with good yield.

Novel substituted bis-(3-cyano-2-pyridone) derivatives were prepared via a powerful method using enaminonitriles push-pull dienes as key building blocks. The synthesis was performed in three steps from easily accessible starting materials in good yields. All target products were structurally elucidated by spectroscopic data. The reaction mechanism for formation of bis (3-cyano-2-pyridone) derivatives was proposed. The structures of enaminonitriles 3a and bis-pyridones 4c were confirmed by single-crystal X-ray diffraction. The florescent study of some bis (3-cyano-2-pyridones) derivatives was reported.

A straightforward strategy for synthesis of highly functionalized trifluoromethyl 2H-furans is described. The copper catalyzed method relies on a cascade cyclic reaction between enaminones and N-tosylhydrazones. This method allows the synthesis of 2-amino-3-trifluoromethyl-substituted 2H-furan derivatives carrying a quaternary stereogenic center as single diastereomers. The proposed reaction mechanism involves an amino-cyclopropane intermediate formed in the cyclopropanation of enaminones. The developed method tolerates a broad spectrum of functionalities, and the obtained 2H-furan derivatives are useful synthetic intermediates for preparing other trifluoromethyl-substituted compounds.

Visible-light active, heterogeneous, and organic photocatalysts exhibit a more sustainable and environmentally friendly alternative to classical metal-based catalysts. Two-dimensional covalent organic frameworks (2D-COFs) with permanent porosity, columnar It-arrays and excellent stability, that can become an excellent platform for heterogeneous photocatalysis of organic transformations. Here we report a predesigned imine-based COF with electron donor and acceptor structure. And new framework possesses large surface area, high crystallinity, outstanding stability and broad absorption range in the visible-light region as well as good photoelectric response characteristics. Importantly, it was found to be a highly effective heterogeneous photocatalyst for reductive dehalogenation of phenacyl bromide derivatives and cc-alkylation of aldehydes under irradiation of visible-light. In addition, the COF gave good recyclability and could be reused after a simple separation manipulation. The current present still reveals a great prospect for 2D-COFs as metal-free, heterogeneous photo catalysts for organic transformations.

Herein, a series of Fe-based catalysts have been designed and prepared by grinding a mixture of MIL-88d and melamine, and then the mixture was followed by pyrolysis. An unusual Fe/Fe3C-activated site is uniformly encapsulated in the N-doped carbon tubes obtained by pyrolysis of the film-like nanocrystals of MIL-88d. Experimental characterizations and theoretical calculations demonstrate that the surface N sites can effectively trap the nitrobenzene and aniline by their phenyl groups with the formation of three C-N bonds that made the catalyst exhibit excellent catalytic activity (turnover frequencies of <= 11268 h(-1) calculated on the basis of nitrobenzene) and chemoselectivity for the reduction of nitro derivatives under facile conditions.

The grafting of a Pt(II) photocatalyst into three different mesoporous silica-based materials with different particle sizes and pore sizes was easily achieved through an amide bond formation. The analysis and results of the different characterization techniques showed that the catalyst is immobilized inside the pores of the materials and the photophysical properties of the catalyst are preserved after the covalent anchoring. The photocatalytic material catalyzed efficiently the debromination reaction of different substrates and is reused without detriment in its catalytic activity. In addition, the incorporation of the catalyst into mesoporous silica materials with different pore size allows the selective debromination of substrates by size discrimination.

There has been a great deal of attention to the development of heterogeneous non-noble metal catalysts for the selective and mild hydrogenation of nitro compounds into primary amines. Herein, a biomass-derived carbon material supported Ni catalyst (Ni/C) was facilely prepared by a one-pot pyrolysis process, and the as-prepared Ni/C catalyst demonstrated a high catalytic activity for the hydrogenation of nitro compounds into primary amines at room temperature. The Ni/C catalyst not only demonstrated a high catalytic activity but also showed a good tolerance to other functional groups. Structurally diverse primary amines were achieved in yields from 92% to 99% within a few hours at room temperature under 5 bar H-2. Furthermore, the Ni/C catalyst showed good reusability without the loss of its activity.

A novel and efficient oxidative esterification for the selective synthesis of alpha-ketoesters and esters has been developed under metal-free conditions. In the protocol, various alpha-ketoesters and esters are available in high yields from commercially available ketones and potassium xanthates. Mechanistic studies have proven that potassium xanthate not only promotes oxidative esterification but also provides an alkoxy moiety for the reaction, which involves the cleavage and reconstruction of C-O bonds.
