Syntheses of enantiopure organosulfur donors by three different strategies requiring only four–six steps are reported. The key step involves either double substitution of an enantiopure cyclic sulfate ester by a dithiolate, attachment of a chiral diol as a ketal, or completely diastereoselective cycloaddition of 1,3-dithiole-2,4,5-trithione to an enantiopure alkene.
报告采用三种不同的策略合成了对映体纯有机硫给体,只需要四到六个步骤。关键步骤包括对映体纯环硫酸酯与二硫醇的双取代、手性二元醇作为酮体的连接,或 1,3-二硫代-2,4,5-三硫酮与对映体纯烯的完全非对映选择性环加成。
