摘要

tized photooxygenation was carried out in methanol at 0" C under an oxygen atmosphere using a 100-W tungstenhalogen lamp without a filter. The absorption of oxygen and the evolution of carbon monoxide were nearly quantitative, and 6-keto acids 4a-d were obtained in more than 90% yield. The reaction was followed by measuring the oxygen absorbed and carbon monoxide evolved using gas chromatography and manometry.
