Synthesis of polycyclic fused 2-quinolones in aqueous micellar system
摘要:
A high yielding green protocol has been developed for the synthesis of tri-, tetra-, and pentacyclic fused 2-quinolones in micellar medium. The method is more effective compared to phase-transfer catalytic (PTC) method in terms of the yield of the product as well as the reaction time. It is operationally simple as well as environmentally benign. (C) 2010 Elsevier Ltd. All rights reserved.

Phase transfer catalyzed one-pot syntheses of fused oxazepino, oxazocino, and oxazonino quinolinium cations and quinolones were achieved from 8-hydroxy quinoline derivatives with 1,omega-dihaloalkanes. Structures of all the products were elucidated by spectroscopic analysis. Single crystal X-ray crystallographic analysis of three compounds and graphical superposition of the structures indicate that products having seven-membered ring are less planar compared to the product having eight-membered ring.
