Abstract
A substituted hydropyrazino[1,2- a]pyrimidin-6-one derivative was synthesized stereoselectively via the intramolecular N-acyliminium ion cyclization between an amide nitrogen and an N α-acetal derived from Cbz-protected aminopropyl-phenylalaninamide in very good yields. The formation of a single diastereomer is due to the low energy chairlike conformation of its bicyclic structure. This methodology provides a convenient tool to build internal bicyclic peptidomimetics.
