Preparation of Chiral, Highly Functionalized Cyclopentenones

During a detailed examination on the cyclization of 1,4-diketones to cyclopentenones, we have found that two oxygenated products (4 and 5) are formed when the purification by column chromatography on silica gel takes a long time.The highly functionalized
