Syntheses of novel bicyclic β-lactams by intramolecular nucleophile transfer reactions of N-tosyloxy β-lactams

Guzzo,Teng,Miller

, p. 8275 - 8292 (2007/10/02)

Intramolecular nucleophile transfer reaction of several N-tosyloxy β- lactams was applied to construct a new six-membered ring in the product bicyclic β-lactams. The bicyclic products generally possessed cis stereochemistry on the β-lactam ring. The major
