Asymmetric cycloaddition of N-metalated azomethine ylides with the optically active α,β-unsaturated esters derived from α-amino acids

α,β-Unsaturated esters bearing a chiral oxazolidine or perhydropyrrolo[1,2-c]imidazole auxiliary at the β-position have been prepared and applied to the cycloadditions with N-metalated azomethine ylides derived from a-(benzylideneamino) esters. These reac
