Abstract

The reported cycloaddition reactions between nonstabilized azomethine ylide Y generated from trimethylamine N-oxide 1 and unactivated C≡C 2 - 4, C=N 5 and C=S 6, 7 bonds constitute an attractive entry respectively to pyrrolines and pyrroles 10 - 13, imidazalidine 14 and thiazolidines 15, 16.
