  Bifunctional chiral auxiliaries 5: The synthesis of 1,3-diacylimidazolidine-2-thiones and 1,3-diacylimidazolidin-2-ones from 1,2-diamines

  摘要：

  Although 1,2-diamines fail to cyclise with urea, phosgene or 1,1'-carbonyl diimidazole, they react with carbon disulphide to give the corresponding imidazolidine-2-thiones. These undergo clean diacylation to give 1,3-diacylimidazolidine-2-thiones which are readily converted to 1,3-diacylimidazolidin-2-ones on treatment with mercury (II) acetate. An alternative two-step route to 1,3-diacylimidazolidin-2-ones uses carbonyl sulphide to effect cyclisation of the 1,2-diamine to the imidazolidin-2-one, which is subsequently diacylated. The ability to convert homochiral 1,2-diamines to homochiral 1,3-diacylimidazolidin-2-ones has also been demonstrated.

• Reaction of Thiocarbonyl Fluoride Generated from Difluorocarbene with Amines
  作者：Jiao Yu、Jin-Hong Lin、Ji-Chang Xiao

  DOI：10.1002/anie.201710186

  日期：2017.12.22

  The reaction of thiocarbonyl fluoride, generated from difluorocarbene, with various amines under mild conditions is described. Secondary amines, primary amines, and o‐phenylenediamines are converted to thiocarbamoyl fluorides, isothiocyanates, and difluoromethylthiolated heterocycles, respectively. Thiocarbamoyl fluorides were further transformed into trifluoromethylated amines by using a one‐pot process

  描述了在温和条件下由二氟卡宾生成的硫代羰基氟化物与各种胺的反应。仲胺，伯胺和邻苯二胺分别转化为硫代氨基甲酰氟，异硫氰酸酯和二氟甲基硫代杂环。硫氨甲酰氟通过一锅法进一步转化为三氟甲基化胺。硫代羰基氟化物在原位生成，并在温和条件下在一锅中迅速完全转化；因此，不需要特殊的安全预防措施。

  An efficient and practical thiocarbonyl surrogate via combination of sulfur and chloroform has been developed. A variety of thiocarbamides and oxazolidinethiones have been established, including chiral thiourea catalysts and chiral oxazolidinethione auxiliaries with high selectivity. Meanwhile, pesticides Diafenthiuron (an acaricide), ANTU (a rodenticide), and Chloromethiuron (an insecticide) were

• Bifunctional chiral auxiliaries 6: Alkylations of enolates derived from 1,3-diacylimidazolidine- 2-thiones and 1,3-diacylimidazolidin-2-ones

  日期：1994.4

  Sodium and potassium enolates of 1,3-diacylimidazolidin-2-ones undergo clean alkylation reactions with reactive alkyl halides; the latter enolates reacting generally more stereoselectively due, it is proposed, to the lower temperature at which the reactions proceed. The reactions are all stereoregular, with the diastereoisomeric identity of products being established unambiguously by the synthesis

  1,3-二酰基咪唑烷基-2-酮的烯醇钠和钾盐与反应性烷基卤化物进行干净的烷基化反应；提议的是，后者由于反应进行的较低温度而通常更立体选择性地发生反应。反应都是立体有规的，通过（2S）-3-苯基-2-甲基丙烷-1-醇的合成可以明确地确定产物的非对映异构身份。在这些反应中的不对称诱导的意义上是与螯合的中间性一致的顺式烯醇化物其中亲电子从面部优先接近外在五元环上的最接近的烷基/芳基上。相反，由于烯醇盐的分解，在烷基化反应中1，3-二酰基咪唑烷-2-硫酮不能作为双官能手性助剂。
