Abstract
Palladium(0) catalysed cascade mono- and bis-cyclisation-anion capture invo lving a wide variety of starter species, terminating species and organotin( IV) anion capture reagents are reported leading to a range of bridged, fuse d 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.
