Prostaglandin type compounds of the formula ##STR1## where X is CH.sub.2 --CH.sub.2, CH.dbd.CH cis or C.tbd.C; Y is CH.sub.2 or O; Z is H, OH, CH.sub.3 or CH.sub.2 OH and R is a linear, branched or cyclo alkyl chain of 3 to 7 carbon atoms, can be prepared by essentially a one-step reaction from a new intermediate of the formula ##STR2## where R represents a linear, branched or cyclo alkyl group of 3 to 7 carbon atoms; P is a removable protective group and z is H, OP,CH.sub.3 or CH.sub.2 OP. The intermediate is useful in making known and new PGEs useful as antihypertensives, gastric acid secretion inhibitors and smooth muscle stimulants.
公式为##STR1##的
前列腺素类化合物,其中X为CH.sub.2 --CH.sub.2,CH.dbd.CH cis或C.tbd.C;Y为CH.sub.2或O;Z为H,OH,CH.sub.3或CH.sub.2 OH;R为含有3至7个碳原子的线性、支链或环烷基链,可以通过基本上一步反应从新的中间体##STR2##制备而成,其中R代表含有3至7个碳原子的线性、支链或环烷基基团;P为可移除的保护基团;z为H,OP,CH.sub.3或CH.sub.2 OP。这种中间体可用于制备已知和新的
