N-Phenylacetylated derivatives of 1-aminoalkylphosphonic acids were synthesized and high enantioselectivity of their hydrolysis by penicillin acylase (EC 3.5.1.11) was demonstrated. Stereoselective enzymatic hydrolysis of racemic 1-(N-phenylacetylamino)alkylphosphonic acids was used for preparation of enantiomeric 1-aminoalkylphosphonic acids. The kinetic regularities of penicillin acylase catalyzed
合成了1-氨基烷基膦酸的N-苯基乙酰化衍生物,并证明了其被青霉素酰基转移酶水解的高对映选择性(EC 3.5.1.11)。外消旋的1-(N-苯基乙酰氨基)烷基膦酸的立体选择性酶水解用于制备对映异构的1-氨基烷基膦酸。建立了青霉素酰基转移酶催化水解的动力学规律,并优化了生物催化过程,以提高光学纯度和光学活性产物的收率。
