A new electrochemical method for the asymmetric oxidative dimerization of cinnamic acidderivatives has been developed. This method enabled the enantioselective syntheses of furofuran lignans, yangambin, sesamin and eudesmin.

An efficient synthesis of (+)-sesamin 1a and (−)-sesamin 1b is described. The key reactions include highly stereoselective aldol condensation of piperonal 7 with the dianion of chiral oxazolidinone 8, followed by intramolecular ring cyclization of aldol product 11 in high yield.
