Total synthesis of (8R)-3-(2-deoxy-.beta.-D-erythro-pentofuranosyl)-3,6,7,8-tetrahydroimidazo[4,5-d][1,3]diazepin-8-ol (pentostatin), the potent inhibitor of adenosine deaminase
The present invention relates to a method for the stereo-selective production of pentostatin comprising an enzymatic transglycosylation reaction between an imidazo-[4,5-d]-[1,3]diazepine compound and a 2'-deoxyribonucleotide, followed by an ruthenium-catalyzed asymmetric transfer hydrogenation.
