A facile and efficient procedure has been developed by one-pot condensation of β-naphthol, aldehydes, and cyclic 1,3-dicarbonyl compounds for the synthesis of 8,9,10,12-tetrahydrobenzo[a]xanthen-11-one or 8,9-dihydrobenzo-[f]cyclopenta[b]chromen-10(11H)-one derivatives catalyzed by p-toluenesulfonic acid under solvent-free and sonication conditions.
β-萘酚、醛和环状 1,3-二羰基化合物的一锅缩合已开发出一种简便有效的方法,用于合成 8,9,10,12-四氢苯并[a]xanthen-11-one 或在无溶剂和超声条件下由对甲苯磺酸催化的 8,9-二氢苯并-[f] 环戊二烯 [b] 色烯-10(11H)-one 衍生物。
