Geminal prostaglandins (P.G.'s) are synthesized which are represented by the general formula: ##STR1## where A is a 4 or 5 carbon atom ring-completing group (CH.sub.2).sub.1+m --X--(CH.sub.2).sub.z where m = 0, 1 or 2, Z = 0 or 1, 0<(m + z)<3, and X is --CH.sub.2 --CH.sub.2 --, --CH.sub.2 --CHOH--, ##STR2## and, when m = 0 and z = 1, is also --CH=CH-- or ##STR3## Y is divalent straight chain alkylene of 4 to 8 carbon atoms or --CH.sub.2 CH=CH(CH.sub.2).sub.3 --; r is alkyl of 4 to 7 carbon atoms; Q is --CO.sub.2 H or --CH.sub.2 OH provided that it is not --CH.sub.2 OH when X = ##STR4## or Y--Q taken together may be heptyl or allyl.
伽美那类前列腺素(P.G.'s)是由以下一般式表示的合成物:##STR1## 其中A是一个4或5个碳原子环补充基团(CH.sub.2).sub.1+m--X--(CH.sub.2).sub.z,其中m = 0、1或2,Z = 0或1,0<(m + z)<3,而X是--CH.sub.2--CH.sub.2--、--CH.sub.2--CHOH--、##STR2## 当m = 0且z = 1时,也是--CH=CH--或##STR3## Y是4至8个碳原子的双价直链烷基或--CH.sub.2CH=CH(CH.sub.2).sub.3--;r是4至7个碳原子的烷基;Q是--CO.sub.2H或--CH.sub.2OH,前提是当X = ##STR4## 或Y--Q一起可以是庚烷或丙烯基。
