The invention provides compounds of the formula 1 which are useful as hypertensive, anti-ulcer, anti-asthmatic and nasal decongestant agents and methods of preparing these compounds: ##STR1## wherein A represents --C.dbd.O or .alpha.--C . . . OH B represents ##STR2## R.sub.1 represents H, lower alkyl or substituted lower alkyl Z represents CH.sub.2 --CH.sub.2 or C.dbd.C in the cis configuration R.sub.2 and R.sub.3, the same or different, represent H or substituted or unsubstituted lower alkyl; Y is --S--, --O-- or --CR.sub.6 R.sub.7 R.sub.4, r.sub.5, r.sub.6 and R.sub.7, the same or different, represent H, substituted or unsubstituted lower alkyl or halogen X is H or OH R.sub.8 is OR.sub.9 or NR.sub.9 R.sub.9 R.sub.9 is H or an alkyl group, and when X is OH and A is .alpha.--C . . . OH then together they may form the group ##STR3## wherein R.sub.10 and R.sub.11, the same or different, are alkyl, hydrogen or a carbocyclic group of 4 to 6 carbon atoms.
该发明提供了化合物1的公式,这些化合物可用作高血压、抗溃疡、抗哮喘和鼻腔解充血剂,以及制备这些化合物的方法:##STR1## 其中A代表--C.dbd.O或.alpha.--C . . . OH B代表##STR2## R.sub.1代表H,较低的烷基或取代的较低的烷基 Z代表CH.sub.2 --CH.sub.2或以顺式配置的C.dbd.C R.sub.2和R.sub.3,相同或不同,代表H或取代或未取代的较低烷基;Y为--S--,--O--或--CR.sub.6 R.sub.7 R.sub.4,r.sub.5,r.sub.6和R.sub.7,相同或不同,代表H,取代或未取代的较低烷基或卤素X为H或OH R.sub.8为OR.sub.9或NR.sub.9 R.sub.9 R.sub.9为H或烷基,当X为OH且A为.alpha.--C . . . OH时,它们可以一起形成##STR3## 其中R.sub.10和R.sub.11,相同或不同,为烷基、氢或4至6个碳原子的碳环基。
