Abstract
Compounds of the formula <FORM:1063951/C2/1> or <FORM:1063951/C2/2> in which R is ribosyl or deoxyribosyl, A is hydrogen, hydroxyl or amino, B is hydrogen, halogen, hydroxyl, amino, -SH, alkylamino of up to six carbon atoms, furfurylamino, or acylamino of up to seven carbon atoms, and X is =CH- or =N-; with the proviso that X is not =CH- when B is hydroxyl or when A is hydrogen and B is amino; are prepared by reacting the corresponding N-hydrogen compounds with a purine riboside, a purine ribotide, a purine deoxyriboside, a purine deoxyribotide, a pyrimidine deoxyriboside or a pyrimidine deoxyribotide (a purine residue if used being different from that in a purine base if used) in an aqueous medium of pH 4-10 at 25-50 DEG C. in the presence of an inorganic phosphate and a pentosyl-transferring enzyme system of an aerobic bacterium. Many suitable micro organisms are listed, and may be used as a culture broth or cell suspension or after disruption of the cells. Specified and/or exemplified products are purine, 6-mercaptopurine, 2-aminopurine, 2,6-diaminopurine, kinetin, 6-methylaminopurine, isoguanine, 6-chloropurine, 6-iodopurine, 8-azaguanine and 6-mercapto-8-azaguanine ribosides and deoxyribosides; and benzoyladenine, 8-azahypoxanthine, benzotriazole and benzimidazole deoxyribosides. Other starting bases are specified.
