Surfactant catalyzed convenient and greener synthesis of tetrahydrobenzo[<i>a</i>]xanthene-11-ones at ambient temperature

Abstract

An efficient and greener protocol for the synthesis of 12-aryl-8,9,10,12-tetrahydrobenzo[a]xanthen-11-one using tetradecyltrimethylammonium bromide (TTAB) at room temperature in water is described.
