  Development of a Commercial Process for (S)-β-Phenylalanine

  摘要：

  The development of a commercial manufacturing route for (S)-beta-phenylalanine 8, a key pharmaceutical building block, is described. The different approaches which were investigated, based on catalytic asymmetric hydrogenation of enamide intermediates and on biocatalysis using acylase and lipase hydrolyses, are compared. The lipase resolution route was chosen for scale-up, and the final two-step process, based on readily available raw materials, is shown to be robust at full manufacturing scale

  This study developed a simple, efficient method for producing racemic β-phenylalanine acid (BPA) and its derivatives via the enantioselective acylation catalyzed by the penicillin G acylase from Alcaligenes faecalis (Af-PGA). When the reaction was run at 25°C and pH 10 in an aqueous medium containing phenylacetamide and BPA in a molar ratio of 2:1, 8 U/mL enzyme and 0.1 M BPA, the maximum BPA conversion

  这项研究开发了一种简单，有效的方法，该方法可通过粪便产碱杆菌（Af-PGA）中的青霉素G酰基转移酶催化对映选择性酰化来生产外消旋β-苯丙氨酸（BPA）及其衍生物。当反应在25：C和pH 10的水介质中以2：1摩尔比，8 U / mL酶和0.1 M的苯乙酰胺和BPA进行时BPA在40分钟时的最大BPA转化效率仅达到36.1％，但是，当pH值和苯乙酰胺与BPA的摩尔比分别提高到11和3：1时，BPA的最高转化效率提高到42.9％。在相对最佳的反应条件下，BPA衍生物的最大转化率在相对较短的反应时间（45-90分钟）内都达到了约50％。产物的对映体过量值（ee p ）和底物的对映体过量值（ee s ）均分别高于98％和95％。这些结果表明，本研究中建立的方法是实用，有效且对环境有益的，可用于对映体纯的BPA及其衍生物的工业生产。
