Pemicotinate, ammonolysis

In Table III (see p. 126) are shown the products and yields obtained34 from the pemicotinates of D-mannose, D-galactose, L-arabi-nose, and D-xylose upon ammonolysis in aqueous medium. The latter pentose nicotinate also gave35 6-( l-deoxy-i>glycerol-l-y )-2-(D-threo-glycerol-l-yl)pyrazine (32). The structure and formation of these heterocyclic compounds will be discussed in Section VI,3 (see p. 124).
