  摘要：

  已经制备了一系列新的衍生自脯氨酸，氨基酸和伯胺的二肽样有机催化剂，用于各种芳族醛和丙酮之间的直接不对称羟醛反应，从而以良好的收率（最高82％）和中等的对映选择性（最高可达90％）提供羟醛产物。 67％ee），只有1 mol％的催化剂负载在盐水中。在相同条件下，芳族醛与环己酮的直接不对称羟醛反应可得到高收率（高达91％）和中等至良好的对映选择性（高达88％ee）和优异的非对映选择性（高达99％dr）的羟醛产物。这些有机催化剂很容易从市售材料中以多克规模合成，并在其结构和立体感方面具有高度的模块化。

  摘要：

  在非手性基团配位的双(二甲基乙二肟)钴(II)–手性共催化剂体系中，作为一种新型的手性共催化剂，制备了在α-或β-碳上含有酰胺基的三级胺，并使用它们进行了不对称氢化反应的研究。通过使用N-[(2S,3S)-2-乙酰氧基-3-二甲基氨基-3-苯基丙酰基]-(R)-α-甲基苯乙胺，光学产率达到了34.5%的ee值；这是迄今为止在该体系下对甲基N-(乙酰氨基)丙烯酸酯进行不对称氢化反应中获得的最高值。当N-[N,N-二甲基-(S)-苯丙氨酰]-α-甲基苯乙胺的α-甲基苯乙胺部分发生构型改变时，甲基N-(乙酰氨基)丙烯酸酯的氢化反应中的立体选择性发生了反转，而通过构型改变对苯偶酰的氢化反应中的立体选择性没有发生反转。从这些事实可以推断，手性氨基酸酰胺与甲基N-(乙酰氨基)丙烯酸酯之间的酰胺基氢键可能作为一种吸引力，增强不对称氢化反应的立体选择性。

  Amidation of amino acids using dichloro(methyl)(3,3,3-trifluoropropyl)silane (MTFPSCl2) and imidazole is described. MTFPSCl2 activates the carboxy group and protects the α-amino group of amino acids. The amidation proceeded with 19 amino acids and 19 amines, including α-branched amines and anilines; the corresponding amino acid amides were synthesized in good-to-high yields (up to 96%) with low-to-no

  Ni2+ complexes derived from simple alpha-amino amides catalyze very efficiently the addition of Et2Zn to benzaldehyde, giving (S)-1-phenylethanol as the major isomer in most cases (94% yield, 97% ee for R=Bn). The nature of the substituent on the amide nitrogen atom seems to play a key role in determining the asymmetric induction observed. (C) 2003 Elsevier Ltd. All rights reserved.

  AbstractIt was found that in the chemical ionization (isobutane) mass spectra of some asymmetric secondary alcohols and α‐amino acids, when a pair of enantiomers (such as R‐ and S‐2‐phenyIbutyric anhydride, R‐ and S‐mandelic acid, R‐ and S‐2‐methylbutanoic acid or R‐ and S‐α‐phenyl ethyl amine) were used as reaction reagents, the relative abundances of characteristic ions formed by the stereoselective reaction between sample and reagent of the same configuration were much higher than those ions formed by the sample and a reagent of a different configuration. The absolute configuration of the sample molecule may be predicted by examination of mass spectra of the sample measured with R‐ and S‐reagent respectively. This approach proved to be a convenient way for determination of the absolute configurations of organic molecules on a micromole level by mass Spectrometry.
• Chymotrypsin inhibitory conformation induced by amino acid side chain–side chain intramolecular CH/π interaction

  Dipeptide amides H-D-Leu-Phe-NH-R have been found to assume a conformation induced by the CH/pi interaction and to inhibit chymotrypsin strongly. A series of benzyl amide derivatives H-D-Leu-Phe-NH-[CH2](n)-C6H5 (n = 0-4) have been assayed for chymotrypsin, They inhibit the enzyme in a competitive manner and the highest inhibition is achieved by the amide of n = 1 (K-1 3.6 x 10(-6) M), The activity enhancement is dependent upon the length of methylene chain, not upon the increase in molecular hydrophobicity, indicating the presence of an optimal distance between dipeptide backbone and C-terminal phenyl group for chymotrypsin inhibition, The C-terminal phenyl group has been found to interact with chymotrypsin stereospecifically, The R-isomer of H-D-Leu-Phe-NH-CH(CH3)-C6H5 is as active as the benzyl amide, while the S-isomer is about twenty-fold less active, When the fluorine atom is introduced at a para-position of the C-terminal phenyl group, the resulting dipeptide H-D-Leu-Phe-NH-CH2-C6H4F-p exhibits about six-times increased inhibitory activity (K-1 = 6.1 x 10(-7) M; this dipeptide is one of the most potent chymotrypsin inhibitors to date), H-1 NMR conformational analyses of these dipeptide amide derivatives show the CH/pi: interaction between D-Leu-isobutyl and Phe-phenyl as a key structural element for chymotrypsin inhibition, These structural examinations strongly suggest that in the inhibitory conformation the C-terminal phenyl group fits the chymotrypsin S-1 site, while the hydrophobic core constructed by D-Leu-Phe CH/pi interaction fits the chymotrypsin S-2 or S-1' site.
