A catalytic enantioselective thioacetalization reaction has been developed. Various aldehydes react with unsymmetrical 1,3- or 1,2-dithiols to furnish chiral, enantioenriched thioacetals in excellent enantioselectivities upon treatment with a nitrated imidodiphosphoric acid catalyst. The transformation is assumed to proceed via a thionium ion intermediate.
已经开发了催化对映选择性硫代缩醛化反应。各种醛与不对称的 1,3- 或 1,2- 二硫醇反应,在用硝化亚氨基二磷酸催化剂处理后,以优异的对映选择性提供手性、对映体富集的硫缩醛。假设转化是通过硫离子中间体进行的。
