Domino reaction sequences leading to the formation of 2:2 adducts between acenaphthenequinone and acetophenone

Abstract

A Michael-aldol domino reaction sequence of acenaphthenequinone with acetophenone in the presence of KOH in methanol solvent leading to the formation of three different 2:2 adducts arising through three distinct reaction sequences is described. Similar sequences leading to a highly substituted furan derivative were observed in the reaction between phenanthrenequinone and acetophenone.
