چکیده

A method for Pd-catalyzed, aminoquinoline-directed arylation of vinylic C-H bonds with aryl iodides has been developed. This reaction represents a rare example of Pd-catalyzed vinylic C-H functionalization of unsubstituted acrylamide, allowing for the highly regio- and stereoselective preparation of Z-olefins. High tolerance to functional groups is observed with good yields and excellent selectivity. It offers a complementary synthetic method to traditional pathways for Z-olefins.

P450-catalyzed asymmetric cyclopropanation of electron-deficient olefins under aerobic conditions.

A variant of P450 from Bacillus megaterium five mutations away from wild type is a highly active catalyst for cyclopropanation of a variety of acrylamide and acrylate olefins with ethyl diazoacetate (EDA). The very high rate of reaction enabled by histidine ligation allowed the reaction to be conducted under aerobic conditions. The promiscuity of this catalyst for a variety of substrates contai...
