Abstract: A stereoselective synthesis of D or L form of 1,4-imino-1,4-dideoxyribose has been achieved by two different approaches. The first begins with resolution of the inexpensive 3,4-dehydroproline. Key steps are a stereoselective dihydroxylation followed by reduction of the carboxylate group to a hydroxymethyl. Alternately, 4-tosyl-2,3-O-isopropylidene derivatives of D- or L-lyxose were converted to the azides. Acid hydrolysis of the methyl glycoside followed by catalytic hydrogenation produces 1,4-imino-1,4-dideoxyribose. These aminoribose derivatives should serve as the basis for the development of specific inhibitors of glycosidases and potentially of NAD glycohydrolases.
