H_6P_2W_(18)O_(62)18H _2O-catalyzed, three-component, one-pot synthesis of indeno[1,2-b]quinoline-7-one derivatives

摘要

In this work, a rapid and efficient one-pot method for the synthesis of indeno[1,2-b]quinoline-7-one derivatives by condensation of 1-naphthylamine, 1,3-indanedione, and different aldehydes in the presence of H_6P _2W_(18)O_(62)18H_2O as a green and reusable catalyst in refluxing acetic acid is described.
