Stereoselective synthesis of 3-fluoro azetidinones via the condensation of 2-fluoropropanethioate lithium enolate with imines

S-Phenyl-2-fluoropropanethioate (1) was treated with lithium diisopropylamide in THF at -78°C to give rise to the lithium enolate, which underwent stereoselective condensation with a variety of aldehyde imines (2) at room temperature to afford the corresp

The Stereoselective Synthesis of 3-Fluoro-azetidinones

3-Fluoro-azetidinones were prepared by both the enolate-imine and ketene-imine condensation reactions.The reactions of fluorinated ketenes with imines were remarkably stereoselective forming products derived from lk reaction topicity.Key Words: β-Lactams;
