<p>Sulfonylurea derivatives represented by general formula (1) or salts thereof and optically active intermediates thereof; a process for producing these compounds; and drugs containing these sulfonylurea derivatives or salts thereof as the active ingredient, wherein R1 represents hydrogen, optionally substituted acyl or alkoxycarbonyl; R?2 and R3¿ represent each alkyl; and * represents an asymmetric carbon atom, provided that the case where the absolute configuration at * is S, R1 is hydrogen, R2 is methyl and R3 is cyclohexyl is excluded. These compounds have an immediate- and short-acting hypoglycemic effect.</p> |
