interrelated strategies for the synthesis of members of the cephalotaxus alkaloid family have culminated in a concise route for the preparation of the parent member cephalotaxine (1). As part of efforts exploring the use of an SET-promoted photocyclization reaction of aryl-substituted silylallyliminium salts to generate the spirocyclic DE unit of the target, we noted that attempts to generate the pentacyclic

A general and preparatively simple access to multisubstituted indolizidines has been developed. The key step involves the fluoride ion induced intramolecular reaction of 2,3-dihydro-4-pyridones with allylsilane located in the side-chain.
