Biocatalysis, a useful and green technology in chemo-, regio-and stereoselective synthesis, has been intensely studied and widely used due to its multiple advantages.Rent years, biocatalysis became of increasing importance for the fine chemicals and pharmaceutical industries.however, enzyme-catalyzed enantioselective and regioselective oxidation of c–h and c-N bond was still a challenge in organic synthesis for enzymatic reactions.This presentation discusses enzyme screening, enzyme engineering and synthetic application of selective oxidation c-h and c-N bond for fine chemicals.

Trifluoromethyl group is one of the most frequently available and promising functional groups in pharmaceutical,agrochemical as well as material molecules.Developing synthetic methods for the synthesis of trifluoromethyl functionalized compounds by trifluoromethylation reactions occupies significant position in modern organic chemistry.On the other hand,as a typical tool of sustainable synthesis,transition metal-free synthesis possesses unique advantages in atom economy,easy product purification as well as excellent eco-tolerance.consequently,transition metal-free trifluoromethylation reactions constitute the most important approaches for accessing trifluoromethylated molecules.herein,the advances in the transition metal-free c—h trifluoromethylation reactions are reviewed for the first time.According to the updated state-of-art,both the catalytic reactions by conventional heating chemistry and the more sustainable photocatalysis are included,covering the trifluoromethylation reactions of c(sp^(3))–h bond,aromatic c(sp^(2))–h bond as well as the non-aromatic c(sp^(2))–h bond in different substrates over the last five years(2017—2021).

c-h Elaboration of Enaminones By cross-coupling Transformation

C-H Elaboration of Enaminones By Cross-Coupling Transformati...

中国化学会第十四届全国有机合成化学学术研讨会

作者： Jie-Ping Wan college of chemistry and chemical Engineering Jiangxi Normal University

Enaminones are highly versatile building blocks showing widespread applications in modern organic synthesis. In our studies on enaminone-based organic synthesis over the past 5 years, we have identified various organic reactions by employing one or more of the transformations on the nucleophilic α-C-H bond, the cleavage of the c(sp)-N bond, the cleavage of the c=c bond, the condensation of the carbonyl, and the c=c bond cycloaddition etc. herein, we present the works we have finished in the last 2 years on the cross-coupling reactions by direct elaboration of the enaminone C-H bonds and related domino reactions.
