A New Method for the Synthesis of [1,4]Diazepino[6,5‐b]indole Derivatives.

Abstract

A New Method for the Synthesis of [1,4]Diazepino[6,5-b]indole Derivatives. -Two alternative routes for the synthesis of diazepinoindole derivatives starting from formylindoles are described. All diazepinoindolium chlorides (III) exhibit antihypoxic activity at the piracetam level and pyridinium chlorides (VI) prove to be even more efficient. -(RYABOVA, S. Y.; ALEKSEEVA, L.
