A facile, efficient and environment-friendly protocol for the synthesis of 14-aryl- or alkyl-14H-dibenzo[a,j]xanthenes has been developed by one-pot condensation of 2-naphthol with aliphatic and aromatic aldehydes in the presence of P2O5 or InCl3 as catalysts undersolvent-free conditions. The present approach offers the advantages of clean reaction, simple methodology, short reaction time, high yield
通过在存在条件下将2-萘酚与脂肪族和芳香族醛进行一锅缩合反应,已开发出一种简便,高效且环境友好的方案,用于合成14-芳基-或烷基-14 H-二苯并[ a,j ]氧杂蒽在无溶剂条件下制备P 2 O 5或InCl 3作为催化剂。本方法具有清洁反应,方法简单,反应时间短,产率高,易于纯化和催化剂经济实用的优点。
