Photocyclization of 4-oxo-4-phenyl-butanoyl amines to δ-lactams
摘要:
Irradiation of 4-oxo-4-phenyl-butanoyl amines affords the corresponding delta-lactams via hydrogen abstraction from epsilon-position. Remarkable diastereoselectivities up to > 99% are obtained. (C) 1998 Elsevier Science Ltd. All rights reserved.
