Oxacycloalkenones are prepared by reacting a cycloalkenone with a base in the presence of a dioxygen source in a suitable solvent and isolating the desired product. 1-Hydroxy 2-oxa-3-oxo-.DELTA..sup.4 steroids are convenient synthetic precursors to 2-oxa-3-oxo-.DELTA..sup.4 steroids which find use in modern clinical therapy.
