Total syntheses of (+)-sesamin (1a ) and (+)-sesaminol (1b), which are major components of sesame lignans derived from Sesamum indicum, were accomplished in a highly stereo-controlled manner. Key steps include an L-proline-catalyzed cross-a ldol reaction, which was accelerated with the aid of bifunctional urea 7, and the construction of a furofuran lignan skeleton through a quinomethide intermediate.

Plant products (+)-sesamin, (+)-sesaminol, (+)-methylpiperitol, (+)-aschantin, and (+)-5'-hydroxymethylpiperitol were synthesized in a highly stereocontrolled manner through l-proline-catalyzed bifunctional-urea-accelerated cross-aldol reaction, followed by biomimetic construction of the furofuran lignan skeleton through a quinomethide intermediate.
