| Abstract: | 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. |
