Autor: Xu Deng, Cheng-Cheng Song, Wen-Jing Gu, Yu-Jie Wang, Lu Feng, Xiao-Jian Zhou, Ming-Qiang Zhou, Wei-Cheng Yuan, Yong-Zheng Chen

Publikováno v: Bioresources and Bioprocessing, Vol 11, Iss 1, Pp 1-9 (2024)

Abstract Regioselective and enantioselective hydroxylation of propargylic C-H bonds are useful reactions but often lack appropriate catalysts. Here a green and efficient asymmetric hydroxylation of primary and secondary C–H bonds at propargylic pos

De Novo Synthesis of α‐Ketoamides via Pd/TBD Synergistic Catalysis

Autor: Jia‐He Chen, Li‐Ren Zhang, Zhang‐Yang Wang, Lu‐Jie Liu, Li‐Ping Tu, Yun Zhang, Yong‐Zheng Chen, Wen‐Yong Han

Publikováno v: Advanced Science, Vol 11, Iss 34, Pp n/a-n/a (2024)

Abstract Precisely controlling the product selectivity of a reaction is an important objective in organic synthesis. α‐Ketoamides are vital intermediates in chemical transformations and privileged motifs in numerous drugs, natural products, and bi

Regiodivergent and stereoselective hydroxyazidation of alkenes by biocatalytic cascades

Autor: Jing-Fei Wu, Nan-Wei Wan, Ying-Na Li, Qing-Ping Wang, Bao-Dong Cui, Wen-Yong Han, Yong-Zheng Chen

Publikováno v: iScience, Vol 24, Iss 8, Pp 102883- (2021)

Summary: Asymmetric functionalization of alkenes allows the direct synthesis of a wide range of chiral compounds. Vicinal hydroxyazidation of alkenes provides a desirable path to 1,2-azidoalcohols; however, existing methods are limited by the control
