This invention relates to a process for the preparation of coformycin, 3-(.beta.-D-ribofuranosyl)-6,7,8-trihydroimidazo[4,5-d][1,3]diazepin-8(R)- ol, through a synthetic route from a new derivative of 9-.beta.-D-ribofuranosyl-purine and other synthetic intermediates involved in the process and their preparation.
本发明涉及一种制备共甲霉素(coformycin)的方法,即通过从9-β-
D-核糖基
嘌呤(9-.beta.-D-ribofuranosyl-purine)的新衍
生物和其他合成中间体参与的合成路线制备3-(β-
D-核糖呋喃糖基)-6,7,8-三氢
咪唑[4,5-d][1,3]二氮杂环-8(R)-醇。同时,本发明还涉及涉及合成中间体的制备方法。
