Abstract

The reaction of 3,6-di-tert-butyl-l,4-dihydropyrrolo[3,2-b]pyrrole and its N,N' -dimethoxycarbonyl derivative with chlorosulfonyl isocyanate (CSI) was investigated. The higher reactivity for the electrophilic reaction and a remarkable electron excessiveness of the system were demonstrated by comparing with those of indole and pyrrole derivatives.
