hydrogens (H-3' and H-2'). When the lithiation of the 5'-O-tert-butyldiphenylsilyl derivative 5 was carried out in the presence of HMPA, an anionic silyl migration took place to give the 3'-C-silylated product 4a. The stannyl version of this reaction was found to be also possible, which has disclosed a highly simple entry to the d4T analogues variously substituted at the 3'-position by manipulating
研究了抗HIV药物司他夫定(d4T)的5'-O保护衍生物与LTMP的反应,目的是锂化乙烯基氢(H-3'和H-2')。当5′-O-叔丁基二苯基甲硅烷基衍生物5的锂化在HMPA存在下进行时,发生阴离子甲硅烷基迁移,得到3′-C-甲硅烷基化产物4a。发现该反应的亚锡烷基形式也是可能的,其已经公开了通过操纵3'-C-锡烷基d4T作为共同中间体而非常简单地进入在3'-位被各种取代的d4T类似物。
