In one aspect, methods of synthesizing clinprost, isocarbacyclin and analogs thereof are described herein which, in some embodiments, permit an abbreviated synthetic pathway in comparison to one or more prior synthetic methods. By providing a compact synthetic scheme, methods described herein can reduce cost, waste and time of clinprost and isocarbacyclin synthesis while facilitating the development and investigation of analogs of these compounds.
An improved synthesis of the title compound and a synthesis of its derivatives are described, in which the regiospecific transformation of the diene into the diol was effectively achieved by using thexylborane.

(+)-9(O)-Methano-Δ6(9α)-PGI1, a more potent carbon analog than carbacyclin, has been synthesized from the Corey lactone by utilizing the intramolecularthermalenereaction as a key step.
A new Prostacyclinanalog, 9(0)-Methano-Δ6(9α)-PGII, was synthesized by utilizing intramolecular pinacolic coupling reaction as the key step and was shown to be more potent than carbacyclin in inhibition of platelet aggregation.
