  An atom-economical, multicomponent condensation of naphthols, aldehydes, and cyclic 1,3-dicarbonyl compounds catalyzed by HY zeolites under solvent-free conditions is reported. This ecofriendly protocol offers several advantages such as a green and cost-effective procedure with excellent yield, shorter reaction time, simpler work-up, recovery, and reusability of metal-free solid acid heterogeneous catalyst and tolerance of a wide range of functional groups. The biological studies such as in vitro anti-microbial activities of the prepared new compounds and cell imaging studies on K562 leukemia cell lines by selected benzoxanthenones are evaluated.

  Abstract An efficient, simple synthesis of 2,3,4,9-tetrahydro-1H-xanthene-1-ones and 8,9,10,12-tetrahydro-11H-benzo[a]xanthen-11-ones is reported by one-pot condensation of 3-dimethylamino-2-cyclohexen-1-ones with hydroxybenzyl alcohols, phenol, and 2-naphthol Mannich bases or their quaternized derivatives. The mechanism of the reaction is believed to involve the formation of the o-quinone methide
