PMR analysis assigns twist and chair predominant conformations to the Rp and Sp diastereomers, respectively ( and ), of thymidine 3′,5′-cyclic N,N-dimethylphosphoramidate, . The twist conformer population of is about 64 (acetone) to 75% (toluene).
PMR分析分别将胸苷3',5'-环N,N-二甲基氨基磷酸酯的Rp和Sp非对映异构体(和)赋予扭曲和椅子主要构象。的扭曲构象异构体总数为约64(丙酮)至75%(甲苯)。
