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
