摘要

The nucleic acid precursor, 5-amino-4-imidazolecarboxamide riboside is now made readily available from inosine (hypoxanthine riboside) by a new degradative reaction in which a purine riboside is converted to an imidazole riboside. The Nl-tosyl derivative of inosine is easily prepared and hydrolyzes in alkali to 5-amino-4-imidazole-N-(tosyl)-carboxamide riboside (11). Hydrazinolysis removes p-toluenesulfonamide from this imide and provides ...
