    摘要: The novel 13,14-dihydro-15-keto prostaglandins E of the invention have remarkable preventive effects against ulcers. Further, the novel 13,14-dihydro-15-keto-prostaglandins E of the invention have an advatage that they have none of side effects which prostaglandin E intrinsically has, or can remarakably reduce such effects of the prostaglandin E. Therefore, the novel 13, 14-dihydro-15-keto prostaglandins E of the invention are effective for animal and human use for treatment and prevention of ulcers, such as duodenal ulcer and gastric ulcer.

    摘要: Highly pure benzyl esters of aromatic hydroxycarboxylic acids are produced in high yields by reacting an aromatic hydroxycarboxylic acid or its lower alkyl ester with a benzyl alcohol in the presence of an organotin compound of the general formula ##STR1## wherein R's are identical or different and each represents an alkyl group having 1 to 8 carbon atoms or an aryl group, and Z represents an oxygen or sulfur atom,an organotin compound of the general formulaR.sub.p SnX.sub.q (II)wherein R is as defined, X represents a halogen atom or the group --OCOR.sup.1 in which R.sup.1 represents a saturated or unsaturated alkyl group having 1 to 18 carbon atoms or an aryl group, p is 2, 3 or 4, q is 0, 1 or 2, the sum of p and q is 4, and when q is 2, the two X's may be linked to each other to form the group --OCO--R.sup.2 --COO-- in which R.sup.2 represents a saturated or unsaturated alkylene group having 1 to 10 carbon atoms or an arylene group,or an organotitanium compound of the general formulaTi(OR).sub.4 (III)wherein R is as defined.
