HYDRAZINE DERIVATIVES OF DEHYDRO-L-ASCORBIC ACID

Condensation of L-threo-2,3-hexodiulosono-1,4-lactone (1) with 2 mol of o-nitrophenylhydrazine gave the bis(o-nitrophenylhydrazone) 2, oxidation of which with cupric chloride afforded 3,6-anhydro-3-(o-nitrophenylazo)-L-xylo-2-hexulosono-1,4-lactone 2-(o-n
