In analogy to the Arbuzov reaction, phosphorylation has been carried out on the N-hydroxymethylated cyclic amides, dioxopiperazine 1, hydantoine 4, and the L-pyrrolidinones 10, 11 and 12, with triethylphosphite and diethyl methylphosphonite, to give the organophosphorous derivatives 2, 3, 5-8, 13-18, respectively. For the first time, strict selectivity has been observed in the enzyme-substrate interaction of esters of organophosphorous acids with the phosphoesterase enzymes phosphodiesterase I and alkaline phosphatase. The enzyme phosphodiesterase I enhances the hydrolysis of esters of phosphonic and phosphinic acids to the corresponding free acids 19-26, whereas alkaline phosphatase catalyzes the hydrolysis of only one of the two diethoxyphosphono groups to monoethoxyphosphono derivatives 27-29. A general synthesis pathway has been developed for enzyme-catalyzed hydrolysis of the above esters.
与阿尔布佐夫反应类似,用三乙基亚磷酸酯和甲基亚磷酸二乙酯对 N-羟甲基化环酰胺、二氧哌嗪 1、海因 4 和 L-吡咯烷酮 10、11 和 12 进行了磷酸化反应,分别得到了有机磷衍生物 2、3、5-8、13-18。在有机磷酸酯与磷酸二酯酶 I 和碱性磷酸酶的酶-底物相互作用中,首次观察到了严格的选择性。磷酸二酯酶 I 能促进膦酸和膦酸酯水解为相应的游离酸 19-26,而碱性磷酸酶只催化两个二乙氧基膦酰基中的一个水解为单乙氧基膦酰基衍生物 27-29。 目前已开发出一种酶催化水解上述酯类的一般合成途径。
