摘要

A definitive synthesis for the potent adenosine deaminase inhibitor (8R)-3-(2-deoxy-P-~- erythro-pento-furanosyl)-3, 6, 7, 8-tetrahydroimidazo [4, 5-d][1, 3] diazepin-8-01 (l) lS and ita 8s isomer 13 is described, beginning with imidazole precursors. Construction of the heterocyclic portion 11 was accomplished by ring closure of the diamine 10 using triethyl orthoformate; 10 was prepared in eight steps from 4-methyl-5-nitroimidazole (4). ...
