The diastereomers of thymidine 3′,5′-cyclic methylphosphonate have been prepared and separated. A use of 13C NMR for the assignment of their phosphorus configurations is demonstrated which should be generally applicable to P-derivatized cyclic nucleotides.
胸苷3',5'-环
甲基膦酸酯的非对映异构体已制备并分离。已证明使用13 C NMR对其
磷构型进行分配,这通常应适用于P衍生的环核苷酸。
