The relative (cis, trans) stereoselectivity of the β-lactam formation is one of the critical issues in the Staudinger reaction. Although many attempts have been made to explain and to predict the stereochemical outcomes, the origin of the stereoselectivit
Catalyst-free, high-yield, and stereospecific synthesis of 3-phenylthio β-lactam derivatives

From the oxygen esters containing sulfur α-substituent, corresponding stannous enolates were prepared by the use of stannous trifluoromethanesulfonate.The enolates reacted with various imines to provide β-lactams.
