Abstract

A general and stereospecific method has been developed for the direct preparation of βD-ribofuranosyl, βD-arabinofuranosyl and 2-deoxy-βD-erythro-pentofuranosyl derivatives of a number of nitrogen heterocycles. The azoles thus far employed include appropriately substituted pyrrole, pyrazole, imidazole, 1,2,4-triazole, indole, imidazo[4,5-c]pyridine, pyrrolo[2,3-d]pyrimidine, pyrro10[3,2-c]pyridine, pyrrolo[4,2-c]pyrimidine, purine, pyrazolo[3,4-b]pyridine and pyrazolo-[3,4-d]pyrimidine. This simple high-yield methodology provided a facile route to the large-scale preparation of biologically significant nucleo-sides, such as 2′-deoxyribavirin, 2-chloro-2′-deoxyadenosine, tuber-cidin, Z'-deoxytubercidin, =sangivarnycin, 2′-deoxytoyocamycin, cade-guomycin, 2′-deoxycadeguomycin, G-cadeguomycin, kanagawamicin, 2′-deoxy-3-deazaguanosine, sG, brunfelsarnidine ribonucleoside and 2′-deoxyribofuranosyl derivative of the antibiotic SF-2140. This procedure appears to be considerably superior to the previously reported glycosylation methods.
