摘要:Aldimines Of A-Amino Esters Derived From Aldehydes Bearing An Alpha-,Beta-Or Gamma-Protected Amino Group Undergo Agoac/r3N Catalysed Cycloaddition To Electronegative Olefins (Dipolarophile). Subsequent Unmasking Of The Amino Group And Lactamisation,Spontaneous In Most Cases,Generates 5-7 Membered Fused And Bridged Bi-And Tri-Cyclic Lactams. The Regioselectivity Of The Lactamisation Is Controlled By Appropriate Choice Of The Dipolarophile. (C) 2002 Elsevier Science Ltd. All Rights Reserved.
