SYNTHESIS OF NOVEL BENZOCHROMENE,BENZOQUINOLINE,BENZOCHROMENOPYRIMIDINE AND PYREIMIENZOQUINOLINE DERIVATIVES

摘要

Benzochromene,benzoquinoline and their derivatives have a wide range of biological activities such as antimicrobial,antiasthmic,antimalarial,antiseptic,hypnotic,CNS and sedative activities.These observations made it of interest to synthesize new tricyclic hetero-cycles which may have potential medicinal applications.The search for new heterocyclic compounds and for novel methods of their synthesis are major areas in contemporary organic chemistry.
