PYRROLOINDOLES. 18. AN UNEXPECTED CHLORINATION REACTION DURING THE SYNTHESIS OF 2,7-DIETHOXYCARBONYL-1H,8H-PYRROLO[3,2<i>g</i>]INDOLE

Abstract

During the E. Fischer type synthesis of 2,7-diethoxycarbonyl-1H,8H-pyrrolo[3,2-g]indole there was discovered an unusual chlorination reaction of the benzene ring in 7-amino-2-ethoxycarbonylindole. It is suggested that the reaction occurs via an electrophilic substitution mechanism.
