Abstract 1,6-Diarylhexane-1,3,4,6-tetraones reacted with 2-aminophenol and acetone according to previously unknown pathway leading to the formation of 3-aryl-3-hydroxy-1-5-[(2-hydroxyphenyl)amino][1,1′-biphenyl]-3-yl}prop-2-en-1-ones. Similar three-component reactions with benzylamine or 2-methoxyaniline afforded mainly 2-(4-aroyl-3-hydroxy-5,5-dimethyl-1,5-dihydro-2H-pyrrol-2-ylidene)-1-arylethan-1-ones
