The invention relates to novel derivatives of 4,5-dihydrooxazoles of the formula ##STR1## in which A denotes --CH.dbd.CH-- or --S--, R.sub.1, R.sub.3 and R.sub.4, independently of one another, denote hydrogen or lower alkyl, R.sub.2 denotes hydrogen or lower alkoxy, and n denotes 0 or 1, a process for their preparation, and pharmaceutical preparations which contain these compounds. The novel compounds cause blockage of H.sup.+ /K.sup.+ ATPase and can be used as active ingredients in medicaments for treatment and prophylaxis of disorders which are caused by increased gastric secretions.
该发明涉及公式为##STR1##的4,5-二氢噁唑的新衍生物,其中A表示--CH.dbd.CH--或--S--,R.sub.1、R.sub.3和R.sub.4独立地表示氢或较低的烷基,R.sub.2表示氢或较低的烷氧基,n表示0或1,以及其制备过程和含有这些化合物的制药制剂。这些新化合物可引起H.sup.+ /K.sup.+ ATPase的阻断,并可用作治疗和预防由胃酸分泌增加引起的疾病的药物的活性成分。
