Abstract

A simple method for the synthesis of acenaphtho[1,2-b]indolindenedione derivatives and acenaphtho[1,2-b]indolone derivatives via four-component reaction is described. The reaction between dimedone, arylamines, acenaphthoquinone, and 1,3-indondione in refluxing ethanol under catalyst-free conditions are produced the title compounds. The advantages of this method are: environmental friendly, short reaction time, easy work-up, and high yield.
