First time one-pot water-mediated synthetic route has been developed by carrying condensation of 2-chloro-3-formyl quinolines and hydrazine hydrate/phenyl hydrazine using thermal/microwave energy resources. The route is convenient, eco-friendly, and scalable. (C) 2010 Elsevier Ltd. All rights reserved.

and baker’s yeast catalyzed, efficient synthetic routes have been first time developed for multicomponent cyclocondensations leading to bioactive tetrahydrobenzo[a]xanthene-11-ones (4a–h) and pyrazolo[3,4-b]quinolines (7a–i). The developed protocols are conducted at roomtemperature and gave better to excellent yields of the titled compounds. The biocatalytical resource, activated baker’s yeast is readily
