A new route to N-substituted heterocycles

Abstract

N-(Benzotriazol-1-ylmethyl)-indole, - pyrrole, -carbazole, and -benzimidazole, and analogs substituted in the methylene group are converted by lithium aluminum hydride, or by Grignard reagents, or in two cases by organozinc reagents, into the N-substituted heterocycles in good yields. © 1993.
