A reliable and novel synthetic route for the preparation of prop-l-ene-l,3-sultone (1) has been developed. An overall yield of 34% could be achieved for this five-step synthesis. The Diels-Alder reactions of 1 with a variety of dienes were investigated for the first time and achieved with good chem
