  Chemocontrolled reduction of aromatic α-ketoesters by NaBH4: Selective synthesis of α-hydroxy esters or 1,2-diols

  摘要：

  alpha-hydroxyesters 5a-g or diols 6a-g have been obtained in high yields by reduction of aromatic alpha-ketoesters 4 once or twice respectively by using NaBH4 as the reducer under suitable conditions. The use of a solvent that does not interact with the reagent allowed the double reduction to occur with only a slight excess of borohydride in very mild conditions. (C) 1997 Elsevier Science Ltd.

  A general and practical cross-dehydrogenative coupling protocol between readily available trisubstituted α,β-dehydro α-amino carboxylic esters and H-phosphites is described. This C(sp2)–H phosphorylation reaction proceeds with absolute Z-selectivity promoted by silver salt in a radical relay manner. The bulky tetrasubstituted β-phosphonodehydroamino acids were obtained in grams and added new modules

  A facile and effective synthesis for a wide variety of 4-arylidene-5-imidazolinone derivatives was developed. 4-Arylidene-5-oxazolinones were prepared by Erlenmeyer azlactone synthesis from N-acylglycines and arylaldehydes. The ring-opening reactions of the 4-arylidene-5-oxazolinones with primary amines afforded 2-acylamino-3-arylacrylamides in excellent yields. A new dehydrative cyclization of the

  设计和开发具有高活性和选择性的坚固且多孔的负载型催化剂对于精细化学品和药物的生态友好合成非常重要，但非常具有挑战性。我们在此报告了具有不同拓扑结构的高度稳定的手性 Zr(IV) 基 MOF 的设计和合成，以支持 Ir 配合物并证明其依赖于网络结构的不对称催化性能。在调制合成和等网状扩展策略的指导下，五个具有flu或ith拓扑结构的手性Zr-MOFs由对映纯的1,1'-联苯酚衍生的四羧酸酯接头和Zr6、Zr9或Zr12簇构建而成。所得MOFs在沸水、强酸性和弱碱性水溶液中均表现出较高的化学稳定性。两种以双酚二羟基为特征的开放笼和大笼中的flu MOF，经过P(NMe2)3和[Ir(COD)Cl]2的连续后合成修饰，可以成为高效且可回收的α加氢多相催化剂具有高达 98% ee 的脱氢氨基酸酯，而在小笼中具有二羟基基团的第三个 MOF 不能与 P(NMe2)3 一起安装以支持 Ir 络合物。将 Ir-磷催化剂掺入

  calculations described in our previous work. This P‐stereogenic bisphosphine ligand possessing a biphenyl backbone and 2,2′‐tert‐butylmethylphosphino groups has been applied to the Rh‐catalyzed asymmetric hydrogenation of enol esters, which has not been widely studied and can be used for the synthesis of several important bioactive compounds. Although there is room for further improvement in enantioselectivity

  这是我们先前有关Atropos联苯双膦配体开发的工作的更新。单晶X射线衍射证实了Atropos出乎意料的结构性能，该结果与我们先前工作中所述的计算结果相符。这种具有联苯骨架和2,2'-叔丁基甲基膦基的P-stereogenic bisphosphine配体已被用于Rh催化的烯醇酯的不对称加氢反应，尚未得到广泛研究，可用于合成几种重要的生物活性化合物。尽管在对映选择性方面仍有进一步改进的余地，但本文报道的结果提供了对这类配体的进一步理解。
