- Enantioselective Deuteration of β-Substituted α,β-Unsaturated Esters by Rhodium-1,2-Bis(2,5-diphenylphospholano)ethane
-
We report an efficient method for the synthesis of a chiral C-CHD-CHD-C unit in threo form, which enables the asymmetric conformational analysis of straight alkyl chains. The vicinal dideuterated compound was constructed by enantioselective catalytic deut

- Total synthesis of (+)-pilosinine via a stereodivergent conjugate addition strategy
-
In recent work, asymmetric conjugate addition reactions to chiral 4-phenyl-N-enoyl-1,3-oxazolidinones have been shown to give different stereochemical outcomes depending on the conditions employed. Through the application of stereodivergent reaction conditions, the total synthesis of (+)-pilosinine and the formal synthesis of (?)-pilosinine has been completed from a single enantiomer of the 1,3-oxazolidinone auxiliary.
