Synthesis of D-glucose-1-C-14 and D-mannose-1-C-14

Abstract: Heretofore , radiochemical yields of sugars position-labeled with carbon-14 have been only 5 to 10 percent. Th is paper reports an improved cyanohydrin synthesis, and the preparation of D-glucose-l-CH and D-rnannose-I-C14 from D-arabinose in y ields of about 50 percent . L ow yields in prior syntheses appear t o have been due to several inefficient steps, and to t he fact that extension of the carbon chain yields a pair of epimeric sugar d erivat ives, t he proportion of which may not favor the desi red epimer… Show more

“…Application of the same sequence to glucose first gave the lactone of glucoheptonic acid and then n-heptanoic acid. Mo~vry (29) reviewed the general applications of the cyanohydrin synthesis, and its value for the preparation of higher sugars was discussed in detail by Iludson (12); others (3,13,32) studied the preparation and hydrolysis of the sugar cyanohydrins, and the synthesis has been recently used to estimate carbonyl groups in hydrocelluloses and reducing sugars (11,39), as well as to obtain sugars co11-taining radioactive carbon (14). The reduction of the sugar acids to hydrocarbon acids, on the other hand, has received little attention since the time of Kiliani. As early as 1860, Lautemann (24) employed concentrated hydriodic acid a t 140" C., or "phosphorus di-iodide" and a little water near 100" C., to reduce lactic t o propionic acid.…”
