  Tandem base-free synthesis of β-hydroxy sulphides under ultrasound irradiation

  摘要：

  Rongalite® 可促进二芳基二硫化物的裂解，在原位生成相应的硫代硫酸盐，然后在超声波辐照下以区域选择性的方式对环氧化物进行简便的开环反应，从而以良好到极佳的收率生成 β-羟基硫化物。这种方法的重要特点是无碱、无味、产率高、反应速度快、操作简单、高区域选择性、成本效益高，而且不需要过渡金属催化剂。值得注意的是，在标准条件下，1,2-二苯基二硒烷与 2-（苯氧基甲基）环氧乙烷的开环反应也能顺利进行，并以极好的收率得到 β-羟基硒化物。

  JandaJel, with its greater spacing between the linear polymeric chains compared to that of polystyrene matrices, is a very efficient support for improving the catalytic efficiency of TBD under SolFC.

  JandaJel由于其线性聚合物链之间的间距比聚苯乙烯基质更大，是一种在SolFC下提高TBD催化效率非常有效的载体。

  Rongaliteo (R) promotes cleavage of disulfides generating thiolate anions that then undergo facile ring opening of epoxides in the presence of K2CO3 to afford alpha-addition products 3 with good to excellent yields. The important features of this methodology are broad substrates scope, high yielding, reasonably rapid reaction rate, high regioselectivity and no requirement of metal catalysts. It should be noted that the thiolate anion attacks the epoxides derived from styrene to produce the corresponding alpha-addition products 3 with high regioselectivity, instead of the beta-addition regioisomer 4 that Could be formed from the attack of the nucleophile at the benzylic position.

  Rongalite® promotes cleavage of diaryl disulphides generating the corresponding thiolate species in situ which then undergo facile ring-opening of epoxides in a regioselective manner under ultrasound irradiation, affording β-hydroxy sulphides in good to excellent yields. The important features of this methodology are base-free, odourless, high yield, reasonably rapid reaction rate, simple workup, high regioselectivity, cost-effective and no requirement of transition metal catalysts. It is noteworthy that ring-opening reaction of 1,2-diphenyldiselane with 2-(phenoxymethyl)oxirane are also conducted smoothly to afford β-hydroxy selenide in excellent yield under the standard conditions.
