Abstract:An efficient stereoselective synthesis of tetrahydro‐1H‐isobenzofuro[4,5‐c]chromene‐1,3(3aH)‐dione derivatives were achieved through a novel [4+2] cycloaddition reaction of 4‐styryl‐2H‐chromenes with cheaply available maleic anhydride. A series of new tetrahydro‐1H‐isobenzofuro[4,5‐c]chromene‐1,3(3aH)‐dione derivatives 21(a–p) were synthesized in good to excellent yield under mild reaction condition with no chromatographic purification. In this reaction, the generation of four new consecutive stereogenic cente… Show more
