## Abstract The 2‐nitrophenylhydrazones 2 of D‐__arabino__‐2‐hexulopyranosonic acid, D‐arabinose, D‐galactose and D‐galacturonic acid are used as precursors to form chiral functionalized 1,2,4‐benzotriazines and benzimidazoles by reductive cyclization methods. Catalytic hydrogenation provided the a
