NEW APPROACHES TO THE SYNTHESIS OF SPERMINE AND SPERMIDINE ALKALOIDS

New approaches to the formation of macrocyclic lactams are described involving successive ring expansion of 8-lactams and other heterocyclic systems.These methods have been used in the synthesis of a number of spermine and spermidine alkaloids including homaline, celacinnine, dihydroperiphylline, chaenorhine and verbascenine.
