formed in this reaction with a full or predominant inversion of configuration at chiral sulfur or with predominant retention of configuration. The steric course of the reaction depends mainly on the size of the dialkylamido group in the sulfinamides and of the alcohols used as nucleophilic reagents. It has been found that bulky reaction components preferentially form sulfinates with retention of configuration
旋光性亚磺酸酯的合成已经通过旋光性亚磺酰胺的酸催化醇解完成。在该反应中形成亚磺酸盐,其中在手性硫处构型完全或主要反转,或构型主要保留。反应的空间过程主要取决于亚磺酰胺中的二烷基酰胺基的大小以及用作亲核试剂的醇的大小。已经发现,庞大的反应组分在保留构型的情况下优先形成亚磺酸盐。已经证明,通过向酸性反应介质中添加无机盐,可以将反应的立体化学结果从转化转变为保留,反之亦然。这种典型的双分子亲核取代反应的不同立体化学,
