ABSTRACT:
The specification describes as antiulcer drug containing as an active ingredient a 2,3-butanediol diester derivative represented by the formula (I): ##STR1## where R.sub.A may for example be a saturated or unsaturated alkyl or phenyl styryl group and R.sub.B may for example be a saturated or unsaturated alkyl, phenyl, phenylalkyl, phenylpropenyl or phenoxyalkyl group. These groups may optionally be substituted. Many of 2,3-butanediol diester derivatives embraced by the formula (I) are novel. Also described are a novel process for preparing such novel 2,3-butanediol diester derivatives. The 2,3-butandiol diester derivatives of the formula (I) has an action to depress strongly the growth of peptic ulcer and has a very low toxicity.
