  The Role of theα-Stereogenic Center in the Control of Stereoselection in the Reduction ofα-Alkyl-β-hydroxy Ketones: A Highly Diastereoselective Protocol for the Synthesis of 1,2-syn-2-Alkyl-1,3-diols

  摘要：

  Accurate investigations on the role played by an alpha-stereogenic center in controlling the reduction of various classes of beta-hydroxy ketones allowed us to set up a general and highly diastereoselective protocol for the synthesis of 2-alkyl-1,3-diols with 1,2-syn relationship. This methodology is based on the conversion of a beta-hydroxy ketone into the corresponding titanium alcoholate that permits us to organize the substrate in a stable and rigid structure, which stereofacially favors attacking hydride ions. The use of THF as solvent makes available a variety of hydride donors that cover a large spectrum of steric demand: the choice of the more appropriate one depends on the conformational stability of the cyclic intermediate. Excellent results are obtained also in the presence of an additional stereogenic center in the beta-position, even if it exerts a concordant or an opposite steric effect with respect to the alpha-substituent.

  1,3-Diketones were reduced to 1,3-diols by using RuCl[N-(tosyl)-1,2-(diphenylethylenediamine) (η6-arene)] in the presence of formic acid and triethylamine. 1,3-Diols were obtained in good chemical yields and with high ee when symmetrical diketones were reduced.

  1,3-二酮通过使用的RuCl减少到1,3-二醇[ N-（甲苯磺酰基）-1,2-（二苯基乙二胺）（η 6 -arene）]的甲酸和三乙胺的存在下进行。当还原对称的二酮时，以良好的化学收率和较高的ee获得了1，3-二醇。

  derived from acyclic ketones reacted with aldehydes to give syn,syn-1,3-diols 7a and 8a with moderate to high diastereoselectivity. The stereochemical outcome can be attributed to a syn-selective aldol reaction and the subsequent 1,2-syn-selective intramolecular reduction.

  在催化量的 TBAF (Bu4NF) 存在下，衍生自无环酮的二甲基甲硅烷基烯醇化物与醛反应，得到具有中高非对映选择性的 syn,syn-1,3-二醇 7a 和 8a。立体化学结果可归因于顺式选择性羟醛反应和随后的 1,2-顺式选择性分子内还原。
