  Solvent and in situ catalyst preparation impacts upon Noyori reductions of aryl-chloromethyl ketones: application to syntheses of chiral 2-amino-1-aryl-ethanols

  摘要：

  As part of medicinal chemistry efforts we found it necessary to develop general syntheses of highly enantiomerically enriched 1-aryl-2-chloroethanols and 1-aryl-2-methylaminoethanols. A survey of literature methods suggested that a truly general approach had not yet been reported, encouraging us to undertake the development of such a methodology. This study describes the design, development, and reduction to practice of a general synthesis of chiral 1-aryl-2-chloroethanols and the transformation of these entities to highly enantiomerically enriched 1-aryl-2-methylaminoethanols. Of particular importance were observations of the impact of solvent and the method of catalyst preparation on the yield and enantiomerical excess of chlorohydrins prepared via Noyori transfer hydrogenations of aryl-chloromethyl ketones.

Only 1.0 mol% of both (salen)CoI 3g and phosphorane 4d are required for cyclic carbonate synthesis, and the catalyst loading could even be lowered down to 0.1 mol%. Under this condition, no polycarbonate formation is detected by NMR analysis. It is proposed that the high efficiency

  我们报道了由磷烷活化（salen）CoI复合物3g形成双功能催化剂，用于在环境温度和1 bar二氧化碳压力下二氧化碳与末端环氧化物或氮丙啶的反应。（salen）CoI 3g和磷烷4d两者仅需要1.0 mol％即可用于环状碳酸酯的合成，并且催化剂的负载量甚至可以降低至0.1 mol％。在这种条件下，通过NMR分析未检测到聚碳酸酯的形成。有人提出，高效率源自磷烷对（salen）CoI的活化，从而形成具有增强的Lewis酸度的磷烷-salen Co（III）络合物，用于亲电活化，同时生成碘离子作为Lewis碱的co-促进环氧化物开环的催化剂。
