The intramolecular cycloaddition reactions of non-stabilized azomethine ylides generated by the condensation of N-aryl glycines and an enantiopure N-allyl-tethered alkenyl aldehyde derived from (S)-phenyl alanine were investigated. The stereoselective reactions led to the formation of novel cis-fused enantiomerically pure octahydropyrrolo[3,4-b]pyrroles, and the strategy was expanded to the synthesis of enantiopure novel heterotricyclic skeletons, perhydrothiazolo[3′,4′-2,3]pyrrolo[4,5-c]pyrroles.
