    Highly diastereoselective addition of chiral H-phosphonate to tert-butylsulfinyl aldimines: a convenient approach to (R)-α-aminophosphonic acids
    摘要:
    A highly diastereoselective nucleophilic addition of chiral H-phosphonate, derived from a readily available TADDOL auxiliary, to (S)-N-tert-butylsulfinyl aldimines is reported. The reaction proceeds at room temperature in the presence of potassium carbonate and yields the corresponding aliphatic, aromatic and heteroaromatic alpha-aminophosphonates with dr >95:5. Subsequent simultaneous removal of both chiral auxiliaries leads to the desired alpha-aminophosphonic acids in very good yields with an (R)-configuration at the stereogenic alpha carbon.

    手性噻吩磺酰胺—对VOA计算的挑战
    摘要:
    合成了2-甲基-N-(1-噻吩-2-基乙基)丙烷-2-磺酰胺(TSA)的两种对映异构体,并记录了它们的VCD,ROA,IR和拉曼光谱。所解决的(S)-TSA X射线结构显示出与两个TSA构象异构体的存在有关的无序关系,该构象因噻吩环的轻微旋转而不同。单斜晶P 2 1的晶胞中有两个分子晶体形成NH···OS和C * H···OS氢键的网。在一系列用于解释光谱的计算级别中,B3LYP功能与def2TZVP基础集相结合,可以令人满意地重现实验VCD和ROA光谱。为了模拟KBr颗粒中TSA对映体的VCD光谱,考虑了具有两个不同噻吩环位置的二聚体和四聚体。在CDCl 3中测得的VCD光谱由于TSA在氯仿中的构象自由度,因此与KBr完全不同。七个TSA构象异构体在金字塔形的N原子处分成两组相反的构型,形成了另外的立体异构中心。但是,每组构象体之间的势垒低于300 K时的热运动能量。因此,所有构象体(但

    substrate activation modes in a catalytic circle is critical for the development of new, powerful synthetic methodologies toward complex and value-added chemicals from simple and readily available feedstocks. Here, we describe a highly selective difunctionalization of imines through incorporation of activation of CO2 by intramolecular N/B Lewis pairs into a copper catalytic cycle. Experimental and computational
    在催化循环中整合不同的底物活化模式对于开发新的、强大的合成方法至关重要,这些方法可以从简单易得的原料中获得复杂和高附加值的化学品。在这里,我们描述了通过将分子内 N/B Lewis 对激活的 CO2 结合到催化循环中来实现亚胺的高选择性双官能化。机理方面的实验和计算研究揭示了一种α-硼烷基酰胺中间体,一种由 CN 双键化形成的属酰胺基路易斯对,实现了前所未有的 固定模式,这与传统的 插入过渡属元素形成鲜明对比债券。独特的环状氨基甲酸产品可以很容易地转化为多功能的 N-羧化 α-硼酸盐。还实现了手性 N-叔丁烷亚磺酰基醛亚胺的高度非对映选择性反应。我们希望我们的发现可以通过将路易斯对化学结合到过渡属催化中来激发选择性多组分反应的进一步发展。

    of diphenylallylimine to nonracemic sulfinimines was investigated. It was found that the reaction with sulfinimines derived from aliphatic aldehydes afforded the products with excellent diastereoselectivity (>99:1), furnishing the product vicinal diamines in very good yields. Application of the formed product vicinal diamines was demonstrated in the total synthesis of the natural product (−)-epiquinamide

  • 2-Pyridylsulfinamides as effective catalysts in the asymmetric alkylation of aldehydes with diethylzinc
    作者:Kavirayani R. Prasad、Omkar Revu
    DOI:10.1016/j.tet.2013.07.061
    日期:2013.9
    Chiral 2-pyridylsulfinamides were shown to be effective catalysts in the alkylation of aryl and alkyl aldehydes with diethylzinc providing the corresponding alcohols in excellent enantioselectivity. Sulfinamide catalysts possessing solitary chirality at the sulfur center produced the product phenethyl alcohol in good enantioselectivity. Diastereomeric sulfinamides possessing chirality at the carbon-bearing nitrogen and at the sulfur of the sulfinamide increased the enantioselectivity of the product alcohols up to >99%. However, there is no effect of the match-mismatch pair of sulfinamide diastereomers on the outcome of the chiral induction of the product phenethyl alcohols. It was conclusively proved that chirality at the sulfur center is mandatory for obtaining good enantioselectivity in the reaction. (C) 2013 Elsevier Ltd. All rights reserved.
