Abstract

A double-component, multimolecular reaction between acetophenone and aromatic aldehydes was achieved under catalysis by the solid-base mixture NaOH/K2CO3, and Kostanecki s triketone, supposed to exist for more than 110 years, was successfully separated for the first time as an accompaniment of a pentane-1, 5-dione or a 1, 2, 3, 4, 5- pentasubstituted cyclohexanol (Scheme 1) and authenticated by spectroscopic and single ...
