A new series of mononucleotide analogues bearing a nonhydrolysable P–C bond instead of the P–O phosphate linkage is presented. We intend to set up an approach that allows the synthesis of β-hydroxyphosphonate nucleoside analogues as a single diastereoisomer. In this respect, the key “sugar-phosphonate” intermediate was obtained through an Arbusov reaction from an iodosugar derivative in which the stereochemistry
介绍了一系列带有不可水解的 P-C 键而不是 P-O 磷酸键的单核苷酸类似物。我们打算建立一种方法,允许将 β-羟基膦酸酯核苷类似物合成为单一的非对映异构体。在这方面,关键的“糖-膦酸酯”中间体是通过阿布索夫反应从碘糖衍生物获得的,其中 β-羟基的立体化学由起始材料的选择决定,并保留在所得的核苷酸类似物中。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
