  Quantitative enzymatic protection of d-amino acid methyl esters by exploiting ‘relaxed’ enantioselectivity of penicillin-G amidase in organic solvent

  摘要：

  The lower enantio selectivity displayed by penicillin-G amidase (PGA) from E. coli in organic solvent has been exploited for developing a facile, fast and quantitative method for protection of esters of various D-amino acids via N-acylation. The feasibility of the deprotection of the acylated products was also demonstrated by employing PGA from two different sources in aqueous media. Experimental results are in agreement with previous calculations based on in silico models of the enzyme active site. (C) 2004 Elsevier Ltd. All rights reserved.

• Direct Amidation of Amino Acid Derivatives Catalyzed by Arylboronic Acids: Applications in Dipeptide Synthesis

  The direct amidation of amino acid derivatives catalyzed by arylboronic acids has been examined. The reaction was generally slow relative to simple amine-carboxylic acid combinations though proceeded at 65–68 °C generally avoiding racemization. 3,4,5-Trifluorophenylboronic and o-nitrophenylboronic acids were found to be the best catalysts, though for slower dipeptide formations, high catalyst loadings
