  α-Chymotrypsin-catalyzed peptide synthesis in frozen aqueous solution using N-protected amino acid carbamoylmethyl esters as acyl donors

  摘要：

  A kinetically controlled peptide synthesis catalyzed by alpha-chymotrypsin was performed in frozen aqueous solution (ice, -24 degrees C). The yield of the peptide was significantly improved by the use of the carbamoylmethyl (Cam) ester as the acyl donor instead of the conventional ethyl ester. The peptide yield increased up to ca. 90% when N-benzyloxycarbonyl (CBZ)-Phe-OCam and H-Phe-NH2 were used as the acyl donor and nucleophile, respectively. Such an improvement of the peptide yield in ice was also observed in the coupling of other CBZ-amino acid Cam esters as acyl donors. Furthermore, this approach was applied to the synthesis of peptides containing D-amino acids. The peptides such as CBZ-D-Phe-Phe-NH2, CBZ-Phe-D-Phe-NH2 and CBZ-D-Phe-D-Phe-NH2 were also obtained in excellent to moderate yields in ice. A high diastereoselectivity towards the L-L peptide was observed when the racemic amino acid Cam ester was used as the acyl donor in ice. (c) 2005 Elsevier Ltd. All rights reserved.

  The superiority of the carbamoylmethyl ester as an acyl donor for the α-chymotrypsin-catalysed segment condensations via the kinetically controlled approach is demonstrated in several model systems carried out in organic media with low water content. Furthermore, this approach is successfully applied to the construction of the Leu-enkephalin sequence via a 4 + 1 segment coupling.

  The direct esterification of carboxylic acids with perfluorinated alcohols mediated by XtalFluor-E is reported. The corresponding polyfluorinated esters are obtained in moderate to excellent yields with a broad range of carboxylic acids, including aromatic, heteroaromatic, aliphatic, and nonracemic chiral substrates, using only a slight excess (2 equiv) of the perfluorinated alcohol. Control experiments

  据报道，由XtalFluor-E介导的羧酸与全氟化醇直接酯化。仅使用稍微过量的（2当量）全氟化醇，就可以以中等到极高的收率，用宽范围的羧酸（包括芳族，杂芳族，脂族和非外消旋手性底物）获得相应的多氟化酯。对照实验表明，该反应不通过的酰基氟化物的形成继续进行，但最有可能通过一个（二乙基氨基）二氟- λ 4硫烷基羧酸盐中间体。

  The superiority of the carbamoylmethyl ester as an acyl donor for the α-chymotrypsin-catalysed kinetically controlled peptide-bond formation is demonstrated in the couplings of an inherently poor amino acid substrate, Ala, with various amino acid residues as amino components and in the couplings of non-protein amino acids such as halogenophenylalanines as carboxylic components. Furthermore, this approach is applied to the amide-bond formation between an amino acid residue and a chiral amine, which is highly diastereoselective.
