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.

An efficient and simple synthesis of pentacyclic quinolonoquinoxalinooxazocines in a one-pot sequence has been performed by unique application of phase transfer catalysis. Preparative simplicity and conceptual novelty of the methodology offer an attractive generalapplication for the synthesis of novel quinoline antibiotics.
