Regioselectivity in electrophilic substitution of 5-aminoindoles and 5-aminoindolines: synthesis of pyrrolo[3,2-e]indoles and isomeric pyrrolo[2,3-f]indoles
摘要:
An FMO Theory prediction that 5-aminoindoles, 5, should react with electrophiles preferentially at C4 rather than at C6 whereas N1-acyl-5-aminoindolines, 6, should react preferentially at C6 rather than C4 is borne out experimentally by the synthesis of a pyrrolo[3,2-e]indole from 5 and pyrrolo[2,3-f]indoles from 6.

A rhodium(III)-catalyzed direct cross-coupling reaction of indolines with maleimides via C–H bond activation was developed. This protocol displays good functional group tolerance, which offers a novel approach to access C7 modified indoline derivatives including maleimide analogues.
