4-Substituted nicotinic acids and nicotinamides. Part II. The preparation of 4-methylnicotinamide riboside
Abstract
An improved method for the synthesis of nicotinamide ribosides is described. Nicotinamide and 4-methylnicotinamide condense with 3,5-di-O-benzoly-D-ribofuranosyl chloride to give the dibenzoylribofuranosides in good yield. The ribosides obtained by mild hydrolysis contain predominantly the β-anomer.
