[reaction: see text] Diastereoselectivity of up to 88% was achieved for the synthesis of an alpha-mercapto gamma-unsaturated phosphonate using the readily available chiral dimenthylphosphonyl ester group and a carbanionic [2,3]-sigmatropic rearrangement. Absolute configuration of the newly formed chiral center of this nonracemic thiol was determined, and the corresponding phosphono thiolane and thiolane
[反应:见正文]使用容易获得的手性二薄荷基膦酰基酯基团和碳负离子[2,3]-σ重排,合成α-巯基γ-不饱和膦酸酯的非对映选择性高达88%。确定了该非外消旋硫醇的新形成的手性中心的绝对构型,并且还立体选择性地制备了相应的膦酰基硫杂环戊烷和硫杂环戊烷S-氧化物。
