Relevant academic research and scientific papers

An efficient asymmetric synthesis of (-)-wodeshiol

An efficient synthesis of (-)-wodeshiol 1 is described. The key reactions include highly stereoselective aldol condensation of piperonal with the dianion of chiral oxazolidinone, subsequent intramolecular ring cyclization of the aldol product 8 and a dias

An efficient asymmetric synthesis of furofuran lignans: (+)-Sesamin and (-)-sesamin

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.

Stereoselective total synthesis of furofuran lignans through dianion aldol condensation

Highly stereoselective total synthesis of (+)-eudesmin, (+)-yangambin, (-)-eudesmin, and (-)-yangambin is described. This method is useful to generate the core skeleton of furofuran rings utilizing modification of Evans asymmetric aldol condensation.
