✦ Synopsis

An efficient synthesis of heliotridine from readily available retronecine was accomplished by nucleophilic displacement of the 7-mesylate, in the 7-mesyl-Q-bentoate of retronecine with various cesium carboxylates in DMF, followed by hydrolysis. The synthetic procedure also permits the ready synthesis of a number of naturally occurring pyrrolizidine alkaloids possessing dissimilar acyl groups at C-7 and C-9.
