- An unusual synthesis of 2-pyridone and 3,5-dihydroxypyridine from a carbohydrate
-
An unusual aromatization to perbenzylated 3,5-dihydroxy-6-(hydroxymethyl)- 2-pyridone was demonstrated utilizing sugar lactam, under strong basic conditions, derived from d-Galactose. 2-Pyridone was efficiently converted into a pharmaceutically relevant s

- Multi gram-scale synthesis of galactothionolactam and its transformation into a galactonoamidine
-
We recently proposed to conduct selective glycosylation reactions after in situ activation of a glycosyl donor promoted by a transition metal complex immobilized in a macromolecular matrix. In order to develop this catalytic entity, a feasible multi gram-

- Direct oxidative amidation of aldoses by iodine in ammonia water
-
Aldopentoses, aldohexoses and the benzylated derivatives reacted with iodine in ammonia water at room temperature to give their corresponding saccharide amides in high yields. The reactions proceeded with oxidation of the aldose hemiacetals by iodine to g
