The Stereoselective Synthesis of 3-Fluoro-azetidinones

Article abstract of DOI:10.1016/0040-4039(91)80058-E

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;
