Diastereoselective photocycloaddition of an axial chiral enamide
摘要:
The axial chiral enamide 3 was prepared from 2-t-butylaniline in two steps (58% overall yield). Its photocycloaddition to benzaldehyde yielded the oxetane 4a as the major product (62% de), the structure of which was elucidated by single X-ray crystallography. (C) 1999 Elsevier Science Ltd.
