The silicon-induced Pummerer reaction of several amido sulfoxides possessing tethered pi-bonds proceeds by way of a thionium/N-acyliminium ion cascade to provide various azabicyclic ring systems. This cascade sequence was applied toward the synthesis of a member of the protoberberine alkaloid family. (C) 1998 Elsevier Science Ltd. All rights reserved.
