A detailed study of tetrathiomolybdate mediated tandem regio- and stereoselective ring opening of aziridine, disulfide formation, reduction of disulfide bond and Michael reaction in a one-pot operation is reported. This constitutes four reactions that take place in one-pot operation. In the reaction of [BnEt3N]4MoS4 with an aziridine derived from cyclohexene and in the absence of Michael acceptor intermediates
一锅操作中,详细报道了四硫代钼酸盐介导的氮丙啶串联区域和立体选择性开环,二硫键形成,二硫键还原和迈克尔反应的详细研究。这构成了一锅操作中发生的四个反应。在[BnEt 3 N] 4 MoS 4的反应中在不存在迈克尔受体的情况下,用衍生自环己烯的氮丙啶的化合物分离并充分表征了磺酰胺基二硫化物和磺酰胺基硫醇。还已经表明,可以在环氧化物存在下选择性地打开氮丙啶环。通过掺入合适的迈克尔受体作为底物的一部分,可以进行分子内的1,4-加成,以高收率合成含硫的无环环状氨基酸酯衍生物和硫代双环[3.3.1]壬烷衍生物。 。
