An efficient synthesis of azetidine-2,3-diones from L-(+)-diethyl tartrate

Chincholkar, Pinak M.,Puranik, Vedavati G.,Deshmukh, Abdul Rakeeb A. S.

, p. 2242 - 2246 (2008/02/10)

A convenient route to enantiopure azetidine-2,3-diones is described. The chiral ketene generated from commercially available L-(+)-diethyl tartrate on Staudinger cycloaddition with different imines gave spiro-β-lactams in good yields. These spiro-β-lactam
