A simple and convenient procedure for the synthesis of 14-aryl-14H-dibenzo[a,j]xanthenes is described through a one-pot condensation of 2-naphthol with aryl aldehydes in the presence of poly(4-vinylpyridinium)hydrogen sulfate as an efficient, cheap, readily synthesized and eco-friendly catalyst in a solvent free media using conventional heating and ultrasound irradiation.
本文描述了一种简便的 14-芳基-14H-二苯并[a,j]呫吨的合成方法,该方法通过在无溶剂介质中使用常规加热和超声辐射,以聚(4-乙烯基吡啶)硫酸氢盐作为高效、廉价、易于合成且环保的催化剂,使 2-萘酚与芳醛一锅缩合而成。
