It was elucidated by 31P nmr spectroscopy that the conversion of 2,2,2-trichloroethoxycarbonylphosphonates to dialkyl trimethylsilyl phosphites by treatment with Me3SiCl-Zn-acetylacetone proceed with retention configuration at phosphorus. In this study, optical active dinucleoside 2,2,2-trichloroethoxycarbonylphosphonates were synthesized and employed as the reaction substrates.
通过31 P nmr光谱阐明,通过用Me 3 SiCl-Zn-乙酰丙酮处理,将2,2,2-三氯乙氧基羰基膦酸酯转化为二烷基三甲基甲硅烷基亚磷酸酯具有在磷处的保留构型。在这项研究中,光学活性二核苷2,2,2-三氯乙氧基羰基膦酸酯被合成并用作反应底物。
