Of the various conceivable ribonucleosides of allopurinol, the N-1-, N-2-, and N-5-isomers (9c-11c) as well as the 1, 5-and 2,5-bis-ribosylated derivatives 6c and 7c have been prepared via stannic chloride-induced glycosylation of bis (trimethylsilyl)allopurinol 4 with acylated ribofuranoses (5). Trimethylsilyl triflate as catalyst in addition produced the O4-ribosylated isomer 8a. – The structures
在别嘌呤醇的各种可能的核糖核苷中,N -1-,N -2-和N -5-异构体(9c-11c)以及1、5和2,5-双核糖基化衍生物6c和7c已经通过氯化锡诱导双(三甲基甲硅烷基)alalpurinol 4与酰化的呋喃核糖核酸酶的糖基化反应制备了(5)。三氟甲磺酸三甲基甲硅烷基酯作为催化剂还产生了O 4-核糖基化的异构体8a。–从UV,1 H和13 C NMR数据确定了产品的结构。–评估了它们的黄嘌呤氧化酶抑制活性。
