Novel intermediates and improvements in the synthesis of acyclic guanine nucleoside prodrugs of the formula (R)-9-[(2-alkanoylmethyl)-4-(aminoacyloxy)butyl]guanine (for example valtamociclovir stearate), including purine salts amenable to one pot alkylation with the acyclic side chain, acyclic 2-amino-6-halo-purine and protected guanine precursors, one pot manipulations thereof and last step work up procedures.
一种无环鸟嘌呤核苷前药的合成中间体和改进方法的新颖方法,其化学式为(R)-9-[(2-烷酰甲基)-4-(氨基酰氧基)丁基]鸟嘌呤(例如硬膜外瓣状病毒酯)包括能够进行一锅法烷基化的嘌呤盐,无环2-氨基-6-卤代嘌呤和保护鸟嘌呤前体,以及一锅法操作和最后步骤的处理程序。
