Abstract

The Michael condensation in the series of 5-aryl-3-arylidene-3H-pyrrol-2-ones and 5-aryl-3-arylidene-3H-furan-2-ones, containing an activated C=C bond, with cyclohexanone was investigated. It  was shown  that  the condensation products were 1,5-dicarbonyl compounds containing a heterocyclic fragment. The enolization of one of  the  oxo  groups, leading to the formation of hydroxypyrrole or hydroxyfuran structures, was demonstrated by the spectral data.
