title: Double bond isomers of cloprostenol.
abstract: The syntheses of five compounds isomeric with the potent luteolytic agent cloprostenol are described. These are the trans-delta 5, cis and trans-delta 4, cis-delta 6 (methyl ester) and cis-delta 13 analogues. The cis-delta 4 isomer is as potent as cloprostenol as a luteolytic agent in hamsters but the others are markedly less so.
