摘要
Palladium(0) catalysed cascade mono- and bis-cyclisation-anion capture involving a wide variety of starter species, terminating species and organotin(IV) anion capture reagents are reported leading to a range of bridged, fused and spirocyclic products. The diastereoselectivity of the bis-cyclisation processes is explained in terms of steric effects in the transition states. (C) 2000 Elsevier Science Ltd. All rights reserved.
