Functional derivatives of 4-oxoazetidine-2-sulfinic acids in asymmetric synthesis of 2-azacepham sulfoxides and their transformation

The enantiomerically pure 2-azacepham sulfoxide 2a was synthesized by stereocontrolled intramolecular cyclization of sulfinates 3 or sulfinamides 8 in the presence of dry hydrogen chloride followed by triethylamine. The cyclization accrued via equilibrate

Synthesis, Structural Characterization and Stereocontrolled Degradation of 2-Azacephams

The enantiomerically pure substituted 2-azacephams 5 were synthesized by intramolecular cyclization of sulfinamides 4.Their absolute configurations were confirmed by X-ray crystal structure determination of (5R,6R)-4-benzyl-2-isopropylidene-5-oxo-5-thia-1
