and (S)-enantiomers of ethyl 3-amino-4-pentynoate in enantiomerically pure form employing the enzyme Penicillin acylase. In the acylation, phenylacetic acid was used as an acylating agent. We have shown that both the acylation and deacylation can be employed and that the activity of the enzyme Penicillin acylase can be controlled by maintaining an appropriate pH of the reaction medium.
β-氨基酸,(S)-3-氨基-4-戊酸乙基酯,是一种手性合成子,用于合成抗血小板药盐酸西米洛非。开发了一种生物催化方法,以使用青霉素酰基转移酶分解对映体纯形式的3-氨基-4-戊酸乙酯的(R)-和(S)-对映体。在酰化中,使用苯基乙酸作为酰化剂。我们已经表明可以同时使用酰化和脱酰作用,并且可以通过维持反应介质的适当pH来控制青霉素酰基转移酶的活性。
