Abstract

The treatment of the 3-[(1-chloro-2-substituted)ethylidene]indol-2(3H)-ones 4, prepared from indol-2(3H)-one 1, with ethyl chloroformate and triethylamine gives the ethy 3-(ethynyl)-2-(ethoxy-carbonyloxy)indole-1-carboxylates 7. Some dimeric derivatives of the intermediate allenes have been isolated.
