  Pd(OAc)₂-Catalyzed Asymmetric Hydrogenation of α-Iminoesters

  摘要：

  An efficient Pd(OAc)(2)-catalyzed asymmetric hydrogenation of alpha-iminoesters was realized for the first time at 1 atm hydrogen pressure and room temperature. Pd(OAc)(2), a less expensive Pd salt with low toxicity, was found to be the most suitable catalyst precursor rather than Pd(TFA)(2) which is usually the catalyst of choice for homogeneous asymmetric hydrogenation. The chiral alpha-arylglycine fragments are widely found in many chiral products and bioactive molecules.

• Brønsted base-catalyzed three-component coupling reaction of α-ketoesters, imines, and diethyl phosphite utilizing [1,2]-phospha-Brook rearrangement
  作者：Azusa Kondoh、Masahiro Terada

  DOI：10.1039/c6ob00739b

  日期：——

  α-ketoesters, imines, and diethyl phosphite under Brønsted base catalysis was developed by utilizing the [1,2]-phospha-Brook rearrangement. The reaction involves the generation of ester enolates via the umpolung process, i.e., the chemoselective addition of diethyl phosphite to α-ketoesters followed by the [1,2]-phospha-Brook rearrangement, and the trapping of the resulting enolates by imines preferentially

  利用[1,2]-磷-布鲁克重排反应，在布朗斯台德碱催化下，开发了α-酮酸酯，亚胺和亚磷酸二乙酯的三组分偶联反应。该反应涉及通过聚对苯二酚过程产生酯烯酸酯，即，将亚磷酸二乙酯化学选择性加成到α-酮酸酯上，然后进行[1,2]-磷-布鲁克重排，以及亚胺比α-酮酸酯和质子优先捕获亚油酸酯。该操作简单的反应可以以高收率提供在α-位具有氧官能度的致密官能化的β-氨基酸衍生物。非对映选择性很大程度上取决于底物和反应温度，这归因于酯烯酸酯向亚胺的添加的可逆性。该方法进一步扩展到α-酮酸酯，β-硝基苯乙烯和亚磷酸二乙酯的反应。
