A short, totalsynthesis of (+)-davana acid, (+)-nordavanone and (+)-davanone, which are principle components of davana oil, is described. The notable features are the use of the Evans syn aldol reaction and cyclic ether formation by an intramolecular SN2 displacement reaction as key steps. Evans aldol - cyclic ether - (-)-linalool - natural product - davana oil
描述了作为达瓦那油的主要成分的(+)-达瓦那酸,(+)-去甲达万烷酮和(+)-达万烷酮的简短,全合成。显着特征是使用Evans syn aldol反应和通过分子内S N 2置换反应形成环醚是关键步骤。 Evans Aldol-环醚-(-)-芳樟醇-天然产物-达凡那油
