Abstract

7-Oxabicycloheptane substituted prostaglandin analogs useful in treating thrombotic and vasopastic disease have the structural formula ##STR1## wherein m is 1, 2 or 3; n is 1, 2, 3 or 4; Z is --(CH.sub.2).sub.2 --, --CH.dbd.CH-- or ##STR2## wherein Y is O, a single bond or vinyl, with the proviso that when n is 0, if Z is ##STR3## then Y cannot be O, and Z is --CH.dbd.CH--, n is 1, 2, 3 or 4; and when Y=vinyl, n=0; R is CO.sub.2 H, CO.sub.2 lower alkyl, CH.sub.2 OH, CO.sub.2 alkali metal, CONHSOR.sup.3, CONHR.sup.3a or --CH.sub.2 --5-tetrazolyl, X is O, S or NH; and where R.sup.1, R.sup.2, R.sup.3 and R.sup.3a are as defined herein.
