Improved Method of Synthesis of 1-Azafluorene and Derivatives

Abstract

Azafluorenes -tricyclic fused nitrogen- containing systems, still remain a little studied group of compounds and information on this group in the literature is also limited. They are of definite interest, however, for among them, have been found quite effective physiologically active substances, with sedative, neuroleptic and adrenolytic activity [1]. Certain derivatives have been found to produce marked effects on the cen tral nervous system of experimental animals [2].
