regulation of a number of key biological processes. Hydrolysis-resistant analogues of Ap(3)A and Gp(3)G, two important members of that family of nucleotides, have been synthesized. P(1),P(2):P(2),P(3)-Bis-methylene diadenosine and diguanosine triphosphates were prepared from O,O-dialkyl methaneselenophosphonates using an original methodology. Whereas the 2-fold addition of the methanephosphonate anion
二磷酸核苷是无处不在的化合物,与许多关键生物过程的调节密切相关。已经合成了该核苷酸家族的两个重要成员Ap(3)A和Gp(3)G的抗水解类似物。P(1),P(2):P(2),P(3)-双-亚甲基二腺苷和双鸟苷三磷酸是使用原始方法从O,O-二烷基甲硒代膦酸酯制备的。尽管不能将甲烷膦酸根阴离子加成两倍到活化的磷物质上,但是锂化的甲烷硒酸膦酸根与亲电三价磷化合物的多重缩合被证明是非常有效的。一锅缩合/酯化/氧化序列涉及O,O-二烷基甲烷硒代膦酸酯提供了通往PCH(2)PCH(2)P主链的高效途径。
