A new and simple procedure has been developed for the synthesis of 2'-amino-2'-deoxyguanosine (9) and -adenosine (15) and related compounds. An enzymatic transaminoribosylation between 2-chlorohypoxanthine (6) and 2'-amino-2'-deoxyuridine (4) afforded 9-(2-amino-2-deoxy-β-D-ribofuranosyl)-2-chlorohypoxanthine (8), which was chemically converted to 9 and its derivatives. 2'-Amino-2'-deoxyinosine (7) enzymatically prepared was also subjected to synthetic processes to give 15 and its derivative. The combination of chemical and enzymatic reactions was found to be useful for the synthesis of some sugar-modified purine nucleosides.
已经开发出一种新的简单方法来合成2'-氨基-2'-脱氧鸟苷(9)和-腺苷(15)及相关化合物。2-氯次黄嘌呤(6)和2'-氨基-2'-脱氧尿苷(4)之间的酶促转氨酰核糖基化反应产生了9-(2-氨基-2-脱氧-β-D-呋喃核糖基)-2-氯次黄嘌呤(8),后者可通过化学方法转化为9及其衍生物。2'-氨基-2'-脱氧肌苷(7)的酶促制备也可通过合成方法转化为15及其衍生物。化学和酶促反应的组合被证明可用于合成一些糖修饰的嘌呤核苷。
