  Synthesis of .gamma.- and .delta.-lactones by free-radical annelation of Se-phenyl selenocarbonates

  摘要：

  A general method for the synthesis of gamma- and delta-lactones through the intramolecular addition of alkoxycarbonyl radicals, formed by reaction of Se-phenylselenocarbonates with n-Bu3SnH, onto carbon-carbon multiple bonds is described. This free-radical cyclization is characterized by high regioselectivity favoring exo addition and by a high ratio of cyclization to reduction. Monocyclic, fused bicyclic, and spirocyclic lactones are formed in good to excellent yield. Use of allyltri-n-butyltin as a chain-transfer agent in the place of n-Bu3SnH affords the corresponding 3-butenyl lactones.

  and waste‐balance (E‐factor down to 2). Chiral substrates are converted with excellent levels of stereochemical inversion (99 %→≥95 % ee). In a practical one‐pot procedure, the primary formed chlorides can be further transformed into amines, azides, ethers, sulfides, and nitriles. The value of the method was demonstrated in straightforward syntheses of the drugs rac‐Clopidogrel and S‐Fendiline.

  简单的甲酰胺催化剂可促进以苯甲酰氯为唯一试剂将醇类有效转化为烷基氯。这些亲核取代是通过亚胺基活化的醇作为中间体进行的。这种新颖的方法甚至可以在无溶剂条件下进行，其特点是具有出色的官能团耐受性，可扩展性（> 100 g）和废物平衡（电子因子低至2）。手性底物的转化具有优异的立体化学转化水平（99％→≥95％ee）。在实际的一锅法中，初步形成的氯化物可以进一步转化为胺，叠氮化物，醚，硫化物和腈。该方法的价值在药物rac ‐ Clopidogrel和S‐芬迪林。

  The present invention relates to a method of converting an alcohol into a corresponding halide. This method comprises reacting the alcohol with an optionally substituted aromatic carboxylic acid halide in presence of an N-substituted formamide to replace a hydroxyl group of the alcohol by a halogen atom. The present invention also relates to a method of converting an alcohol into a corresponding substitution product. The second method comprises: (a) performing the method of the invention of converting an alcohol into the corresponding halide; and (b) reacting the corresponding halide with a nucleophile to convert the halide into the nucleophilic substitution product.

  本发明涉及一种将醇转化为相应卤化物的方法。该方法包括在N-取代甲酰胺的存在下，将醇与可选择取代的芳香羧酸卤化物反应，以通过卤原子取代醇的羟基。本发明还涉及一种将醇转化为相应取代产物的方法。第二种方法包括：(a)执行将醇转化为相应卤化物的本发明方法；以及(b)将相应卤化物与亲核试剂反应，将卤化物转化为亲核取代产物。
