aziridinomitosenes had been developed from l-serine methyl ester hydrochloride. The tetracyclic target ring system was assembled by an internalazomethineylidecycloadditionreaction based on silver ion-assisted intramolecular oxazole alkylation and cyanide-induced ylidegeneration via a labile oxazoline intermediate (62 to 66). Other key steps include reductive detritylation of 26, methylation of the N-H
