A synthesis of (−)-crobarbatic acid is reported along with the first use of a vinyl-substituted ketene dithioacetal as a coupling partner for an anodic cyclization reaction. The use of the vinyl-substituted ketene dithioacetal enables the construction of a cyclic product having a tetrasubstituted carbon with a relative stereochemistry opposite to that originally obtained from the cyclization.
报道了(-)-crobarbatic酸的合成,以及首次使用乙烯基取代的乙烯酮二硫缩醛作为阳极环化反应的偶联伴侣。乙烯基取代的烯酮二硫缩醛的使用使得能够构建具有四取代的碳的环状产物,其相对立体化学与最初从环化获得的立体化学相反。
