Novel syntheses of polysubstituted pyrroles and oxazoles by 1,3-dipolar cycloaddition reactions of benzotriazole-stabilized nitrile ylides

1,3-Dipolar cycloadditions of benzotriazole-stabilized nitrile ylides with benzyl α,β-unsaturated-carboxylates and aldehydes as dipolarophiles proceeded smoothly and efficiently to give polysubstituted pyrroles and oxazoles, respectively, in good yields.
