Abstract

Benz[f]indole, of which few effective preparative methods are known, was easily synthesized by palladium-catalyzed reaction of ethyl 3-bromo-2-naphthylcarbamate with trimethyl-silylacetylene and subsequent cyclization with sodium ethoxide in ethanol. By the same method, benz[g]indole and benz[e]indole were obtained from 2-bromo-1-naphthylcarbamate and 1-bromo-2-naphthylcarbamate, respectively.
