Biologically interesting 9 (O)-methano-△6-prostaglandin I1 (9 (O)-methano-△6-PGI1), a chemically stable analog of prostacyclin (PGI2), was efficiently synthesized from 1, 3-cyclooctadiene with high stereo- and regiochemical control. In all three biological test systems examined, 9 (O)-methano-△6-PGI1 was found to be considerably less active than prostaglandin E1 (PGE1).
