    AbstractA novel selective two-step synthesis of β-isothiocyanato ketones from α,β-unsaturated ketones has been developed. The synthesis includes preparation of β-azido ketones followed by reaction with triphenylphosphine and carbon disulfide. Treatment of the obtained β-isothiocyanato ketones with ammonia or methylamine gives corresponding hexahydro-4-hydroxypyrimidine-2-thiones. The latter are also
    摘要从α,β-不饱和酮开发了一种新颖的选择性两步合成β-异硫氰酸根酮的方法。合成包括制备β-叠氮基酮,然后与三苯基膦和二硫化碳反应。用氨或甲胺处理所得的β-异硫氰酸根合酮,得到相应的六氢-4-羟基嘧啶-2-硫酮。后者也可以直接由β-叠氮基酮制备,而无需分离中间体β-异硫氰酸根酮。 图形概要

  • Intramolecular, Reductive Cyclization of ?-Ketoisothiocyanates Promoted by Using Samarium Diiodide
    作者:Min Seok Cho、In Sang Lee、Sung Ho Kang、Yong Hae Kim
    DOI:10.1002/chem.200400676
    日期:2005.2.18
    A novel samarium diiodide (SmI2) promoted intramolecular cyclization of beta-ketoisothiocyanate, derived from alpha,beta-unsaturated esters and ammonium thiocyanate led to alpha-hydroxythiolactams and/or thiolactams in high yields. Treatment of beta-ketoisothiocyanate with two equivalents of SmI2 gave a mixture of alpha-hydroxythiolactam and thiolactam. Four equivalents of SmI2 afforded only thiolactam
    新型的二碘化((SmI2)促进了α-β-不饱和酯和硫氰酸铵衍生的β-酮异硫氰酸酯的分子内环化反应,从而高产率地产生了α-羟基硫代内酰胺和/或硫代内酰胺。用两当量的SmI 2处理β-酮异硫氰酸酯,得到α-羟基硫代内酰胺和硫代内酰胺的混合物。四当量的SmI2仅提供高收率的硫代内酰胺。分子内环化反应具有很高的立体选择性。提出了一种解释这种转变的机制。
