  Synthesis of trimethyl .alpha.-keto trithioorthoesters and dimethyl .alpha.-keto dithioacetals by reaction of esters with tris(methylthio)methyllithium

  摘要：

  A complete study has been made of the reaction of tris(methylthio)methyllithium with aromatic, heteroaromatic, and aliphatic esters. It is a one-pot reaction that despite its complexity, and depending on the reagent ratios, the reaction conditions, and the possible use of additional reagents (N-(methylthio)phthalimide or BuLi), can supply easily, in excellent and reproducible yields, the trimethyl alpha-keto trithioorthoesters 3 or, alternatively, the dimethyl a-keto dithioacetals 4. The reaction mechanism has been elucidated.

  Reaction of trimethylsilyl sulphide with phenyl isocyanate gives a 1 : 1 insertion product, but subsequent insertion of phenyl isocyanate takes place readily in the case of trialkylstannyl sulphide, to produce triphenyl isocyanurate. When chloral is used as a reactant for trialkyltin sulphides, substitution of all three chlorine atoms occurs, to afford trialkyltin chloride and (RS)3C·CHO, although

  三甲基甲硅烷基硫醚与异氰酸苯酯的反应生成1：1的插入产物，但是在三烷基锡烷基硫醚的情况下，异氰酸苯酯的随后插入很容易发生，从而生成异氰脲酸三苯酯。当将氯醛用作三烷基锡硫化物的反应物时，尽管在三烷基甲硅烷基硫化物的情况下获得了简单的插入产物，但所有三个氯原子都被取代，从而得到三烷基氯化锡和（RS）3 C·CHO。β-丙内酯的烷基-氧键裂解已选择性地与Si-S化合物反应。

  A study was made of the isomerization reaction of a great variety of trimethyl alpha-keto trithioorthocarboxylates to alpha,alpha-bis(methylthio) thiolcarboxylates, intermediates of high synthetic value for the synthesis of alpha-arylpropionic acids. The reaction was carried out In methylene chloride in the presence of catalytic amounts of trityl perchlorate or methanesulfonic acid and was complete in 2 h at rt. In most of the investigated cases the result was positive, the yields usually being greater than 90%. Also the reaction mechanism was subjected to an experimental study.
