prepared and characterised. Dimethyl (4, 7) and diethyl (5, 8) uracilmethylphosphonates have been prepared by the reaction of chloromethyluracil isomers 2 and 3 with trimethyl phosphite and triethyl phosphite, respectively. The corresponding free acids, 5-uracilmethylphosphonic acid 6 and 6-uracilmethylphosphonic acid 9, have also been isolated. The structure of the compounds has been assigned by nmr spectroscopy
设计,制备和表征了衍生自尿嘧啶和胸腺嘧啶的新型膦酸酯配体。二甲基(4,7)和二(5,8)uracilmethylphosphonates已经制备由氯甲基尿嘧啶的反应异构体2和3分别与亚磷酸三甲酯和亚磷酸三乙酯。还分离了相应的游离酸5-尿嘧啶甲基膦酸6和6-尿嘧啶甲基膦酸9。化合物的结构已通过核磁共振光谱确定,在8的情况下,已通过X射线分析确认。
