• Asymmetric Hydrogenation with Highly Active IndolPhos-Rh Catalysts: Kinetics and Reaction Mechanism

  The mechanism of the IndolPhos–Rh‐catalyzed asymmetric hydrogenation of prochiral olefins has been investigated by means of X‐ray crystal structure determination, kinetic measurements, high‐pressure NMR spectroscopy, and DFT calculations. The mechanistic study indicates that the reaction follows an unsaturate/dihydride mechanism according to Michaelis–Menten kinetics. A large value of KM (KM=5.01±0

  通过X射线晶体结构测定，动力学测量，高压NMR光谱和DFT计算，研究了IndolPhos–Rh催化的前手性烯烃不对称氢化的机理。机理研究表明，根据米利斯（Michaelis-Menten）动力学，该反应遵循不饱和/二氢键机理。K M的较大值（K M = 5.01±0.16  M），表明Rh-溶剂合物是催化剂的静止状态，已通过高压NMR光谱观察到。通过实验手段无法检测到的底物-催化剂复合物的DFT计算表明，主要的底物-催化剂复合物导致了产物。这种机理与先前关于与C 1对称的异位和单齿配体的不对称氢化反应机理的研究一致。

Herein, a simple and efficient stereoselective organocatalytic α-amidoalkylation of dimethyl phosphite by 1-(N-acylamino)alkyltriphenylphosphonium salts to enantiomerically enriched α-aminophosphonates is reported.

  α-氨基膦酸是α-氨基酸的磷类似物。由于其独特的生物活性，这种类型的化合物在医学和作物保护中有着广泛的应用。这些活动中的一个关键因素是立体异构体的构型。迄今为止，只有少数将 α-氨基酸立体选择性地转化为磷类似物的方法是已知的，而且所有方法都基于不对称诱导，因此涉及手性底物的使用。相比之下，我们专注于开发一种使用起始 N-保护的 α-氨基酸和手性催化剂的外消旋混合物进行此类转化的有效方法。在此处，报道了通过 1-（N-酰基氨基）烷基三苯基鏻盐对亚磷酸二甲酯进行简单有效的立体选择性有机催化 α-酰胺烷基化反应生成对映体富集的 α-氨基膦酸酯。使用 5 mol% 的手性奎宁或氢奎宁衍生的季铵盐，最终产品的产率高达 98%，ee 高达 92%。起始鏻盐很容易从α-氨基酸衍生物通过脱羧甲氧基化和随后用三苯基鏻四氟硼酸盐取代获得。通过非手性快速色谱对选定的 α-氨基膦酸酯衍生物进行适当的对映体自歧化 (SDE)
• Enantioselective Synthesis of <i>H</i>-Phosphinic Acids Bearing Natural Amino Acid Residues

  DOI：10.1021/jo400798f

  日期：2013.7.19

  The first systematic study on the asymmetric synthesis of H-phosphinic acids bearing natural protein amino acid residues was reported on the basis of the asymmetric addition of ethyl diethoxymethylphosphinate to N-tert-butane-sulfinyl imines. Good yields and moderate to high enantiose-lectivities were obtained. Reliable methods were developed for the elucidation of the stereochemistry of these phosphinic acids and derivatives thereof. The transformation of the side chains of these analogues was studied. Methods for the conversion of the alpha-aminophosphinates to oligopetides were reported.
• Penicillin G acylase-mediated kinetic resolution of racemic 1-( N -acylamino)alkylphosphonic and 1-( N -acylamino)alkylphosphinic acids and their esters

  Extensive studies on the penicillin G acylase-mediated kinetic resolution of N-acylated 1-aminoalkylphosphonic and 1-aminoalkylphosphinic acids as well as their esters were carried out to recognise the relationships between the substrate structure, reaction conditions, and the enzymatic hydrolytic deacylation efficiency and stereoselectivity. Reactivity of 1-(N-acylamino)alkylphosphonic and 1-(N-acylamino)allcylphosphinic acids and their esters in the penicillin G acylase-mediated hydrolytic deacylation reaction depends strongly on the kind of their N-acyl group, with high preference to the hydrolytic splitting of the N-phenylacetyl moiety. The initial hydrolysis rates of 1-(N-phenylacetylamino)alkylphosphonic acid dimethyl esters 2 are mostly distinctly lower in comparison with the corresponding free acids 3 and rapidly decrease with the increasing steric effect of the substituent at the alpha-position. In contrary to the substituents at the alpha-carbon, bulky substituents at the phosphorus hinder the enzymatic hydrolysis to a much lesser degree. The penicillin G acylase-mediated stereospecific hydrolysis of N-acyl group of both racemic 1-(N-acylamino)alkylphosphonic acids 3 and their dimethyl esters 2 proved to be, in most cases, a highly effective method for the kinetic resolution of these compounds: High enzyme enantioselectivity E-values exceeding 100, or synthetically useful E-values exceeding 20 (in two cases) were obtained for the N-acylated phosphonic acid analogues of alanine, phenylalanine, valine, leucine, and asparagine, as well as for their dimethyl esters, with the exception of the dimethyl ester of phosphonic analogue of valine 2e, that E-value was low (E=1.2). Also for the N-acylated H-phosphinic acid analogues of alanine, as well as phenylphosphinic acid analogue of alanine, high enzyme enantioselectivity values exceeding 100 were obtained. In contrary, E-values for both diastereomers of ethyl ester of phenylphosphinic analogue of alanine 2k were low (E=7 and 13). For the all accomplished assignments penicillin G acylase exhibited stereochemical preference for the (R)-substrate. (C) 2016 Elsevier B.V. All rights reserved.

  日期：1999.8.1

  [GRAPHICS]Cationic rhodium catalysts of the C-2 symmetric DuPHOS (1) and BPE (2) ligands have demonstrated the ability to asymmetrically hydrogenate a novel series of enol phosphonates (3) in good to excellent enantiomeric excess under mild conditions. Initial studies toward the catalytic asymmetric hydrogenation of enamido phosphonates (6 and 7) using the DuPHOS-Rh+ catalysts are also reported.
