    摘要: PROBLEM TO BE SOLVED: To obtain the subject new compound having hypoglycemic action which is equal to or more effective than in the conventional medicine, and is immediately effective and transiently acting, and having extraordinarily little side-effect such as hyproglycemia, etc. SOLUTION: This compound is expressed by formula I [R is H, a (substituted)acyl or an alkoxycarbonyl; R and R are each an alkyl; *expresses an asymmetric carbon atom], e.g. (R)-4-(1-acetoxyethyl)- N-[cyclohexylamino)carbonyl]benzenesulfonamide. The compound is obtained e.g. by the following steps: (1) reacting a sulfonyl chloride derivative of formula II with an ammonium to obtain a sulfonamide derivative; (2) oxidizing the benzyl-site of the sulfonamide to convert it into a ketone; (3) reducing the ketone into a hydroxy product; (4) combining it with an acyl group or an alkoxycarbonyl group to obtain an ester or a carbonate respectively; (5) converting it into a sulfonyl urea to obtain a sulfonyl urea derivative of formula III [R is a (substituted)acyl or an alkoxycarbonyl]; (6) hydrolyzing it.
