Diastereoselective synthesis of bis-beta-lactams

Schiff bases derived from (±)-4-aldehydo-2- -azetidinones react with acid chlorides and triethylamine to produce (±)-bis-β-lactams in a diastereoselective fashion. The steric course of β-lactam fonnation was determined in one case by using chiral HPLC sep
