An efficient and simple procedure for the synthesis of 12-aryl- or 12-alkyl-8,9,10,12-tetrahydrobenzo[a]xanthen-11-one derivatives has been described. This one-pot multicomponent reaction involves the reaction of aldehydes, 2-naphthol, and cyclic 1,3-diketones in the presence of catalytic amount of recyclable TBAF in water.
已描述一种高效简单的合成12-芳基或12-烷基-8,9,10,12-四氢苯并[a]荧蒽-11-酮衍生物的程序。这种“一锅法”多组分反应涉及在可回收的催化剂TBAF(四丁基氟化铵)存在下,用水作为溶剂,反应醛、2-萘酚和环状1,3-二酮。
