Abstract The reaction of N-arylsulfonyl-1,4-quinone diimines with 3-aryl-aminocrotonates gives 1-aryl-2-methyl-3-carbethoxy-5-arenesulfonamidoindoles, i.e., the enamine nitrogen atom participates in the formation of the pyrrole ring; in the case of quinone diimines with two different arylsulfonyl substituents, the arenesulfonamide with the more electronegative substituent is cleaved.
