Abstract EN

C-Alkyl-N-arylmethanonitrilimines 2a, b react with some dipolarophiles 3, 5, 8, 10, 12, and thioxoanilide derivatives 14a-d to give the cycloaddition products, pyrrolo [3, 4-c]pyrazole 4, 4-cyanopyrazole 7, [1, 2-c] pyrazole 9, [1, 2, 4]triazolo[3, 4-a] isoquinoline 11, 13, and 1, 3, 4-thiadiazole 17 derivatives.
