Chlorides Derived from 1-Ethynylcyclohexanol¹

Abstract

Some 3-acylcatechols are synthesized by an orthodox method. Their infrared spectra are recorded. 2,3-Dihydroxy acetophenone is utilized in the preparation of some chalcones, flavanones, and 8-hydroxyflavone. The latter has also been prepared via Claisen condensation of 2,3-dimethoxyacetophenone with ethyl benzoate followed by demethylation and cyclization.
