A new method for the mild sulfurization of phosphorus(III) compounds with thiiranes catalyzed by ReOCl3(PPh3)2 (I) or ReOCl3(SMe2)OPPh3) (II) is reported. The novel catalytic sulfur transfer reactions are rapid and occur efficiently under ambient conditions in organic solvents. This methodology enabled propylene sulfide to be used as a sulfurizing agent for the synthesis of a protected nucleotide phosphorothioate
报道了一种新的用ReOCl 3(PPh 3)2(I)或ReOCl 3(SMe 2)OPPh 3)(II)催化硫醇对磷(III)化合物进行轻度硫化的方法。新颖的催化硫转移反应快速且在环境条件下在有机溶剂中有效发生。这种方法使硫化丙烯可以用作合成受保护的核苷酸硫代磷酸酯的硫化剂。
