  摘要：

  AbstractA series of dialkyl α‐diazophosphonates has been prepared from natural amino acids. The diazo decomposition of these diazophosphonate compounds with tetrakis(acetonitrile)copper(I) hexafluorophosphate/iodine, [Cu(MeCN)4]PF6/I2, as catalyst has been investigated. It was found that the diazo decomposition of dialkyl α‐diazophosphonates gave a mixture of β,γ‐dihydrogen shift and 1,2‐hydride migration products and afforded β‐alkenyl‐substituted β‐amino phosphonates with the Z configuration. The mechanism of this novel diazo decomposition process was discussed.magnified image

  摘要：

  A Highly stereoselective Gabriel reaction via dynamic kinetic resolution utilizing 2-oxoimidazolidine-4-carboxylate as a chiral auxiliary was exploited. The reaction of tert-butyl (4S)-1-methyl-3-(2-bromopropionyl)-2-oxoimidazolidine-4- carboxylate (2a) with potassium phthalimide at room temperature predominantly afforded tert-butyl (4S)-1-methyl-3-((2S)-2-(phthaloylamino)propionyl)-2- oxoimidazolidine-4-carboxylate ((S,S)-5a) in a good yield which was derived to L-alanine derivative (7) by removal of the chiral auxiliary.

• Enantioselection in peptide bond formation
  作者：Roger R. Hill、David Birch、Graham E. Jeffs、Michael North

  DOI：10.1039/b211914e

  日期：2003.3.13

  Selectivity in abiotic condensations of amino acids remains controversial and stereochemically little explored. We find that competitive activated couplings of N-acyl derivatives of glycine, alanine, valine, proline and phenylalanine with binary, ternary and quaternary mixtures of amides and esters of the same group of amino acids show little selectivity among the reactants, except with respect to configuration, where a consistent and significant preference for heterochiral outcomes, mostly >80%, is observed. One possible explanation of this selectivity predicts a predisposition to homochiral coupling under conditions that would require the two carboxyl functions to be co-facial in the activated complex.

  无机物促成的氨基酸缩聚反应中选择性仍然备受争议，而立体化学方面的研究甚少。我们发现，以酰胺和酯组成的双组分、三组分以及四组分混合物为底物，对甘氨酸、丙氨酸、缬氨酸、脯氨酸和苯丙氨酸的N-酰基衍生物进行竞争性活化偶联的反应中，产物在底物分子层面选择性较低，但对映异构选择性较高，选择性系数大多大于80%。此类反应中优先生成异手性产物的一种可能的解释是，在两个羧基必须共面的活化复合物中，同手性偶联具有倾向性。

  日期：——

  2,4-Bis(trifluoromethyl)phenylboronic acid is a highly effective catalyst for dehydrative amidation between carboxylic acids and amines. Mechanistic studies suggest that a 2 : 2 mixed anhydride is expected to be the only active species, and the ortho-substituent of boronic acid plays a key role in preventing the coordination of amines to the boron atom of the active species, thus accelerating the amidation

  A Lewis-acid-catalyzed method for the substrate-directed formation of peptide bonds has been developed, and this powerful approach is utilized for the new "remote" activation of carboxyl groups under solvent-free conditions. The presented method has the following advantages: 1) the high-yielding peptide synthesis uses a tantalum catalyst for any amino acids; 2) the reaction proceeds without any racemization;
