1, 3-Dipolar cycloaddition reactions of benzo[b]thiophene 1, 1-dioxide with azomethine ylides

New pyrrolo derivatives of benzo[b]thiophene 1, 1-dioxide have been synthesised via 1, 3-dipolar cycloaddition reactions. Reaction of benzo[b]thiophene 1, 1-dioxide with stabilised azomethine ylides gave products in low yield but high stereoselectivity whereas reaction with non-stabilised azomethine ylides gave high overall yields but low stereoselectivity.
