A step-economical synthesis of clinprost is reported that concludes with 3 different transition metal-catalyzed reactions: Pd-catalyzed decarboxylation with allylic rearrangement, Rh-catalyzed diene-ene [2+2+1] reaction, and Ru-catalyzed cross-metathesis reaction. The complexity bestowed to the molecule from these reactions converts a readily accessible ester to clinprost without using protecting groups

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.

We describe the effect of allylic (C15) and homoallylic (C11) substituents on cross metathesis reactions with Corey lactone derivatives. This strategy has led to the successful syntheses of PGF(2 alpha) and PGJ(2). (c) 2006 Elsevier Ltd. All rights reserved.

[GRAPHICS]A cross metathesis ( CM) approach has been successfully applied to introduce fully functionalized omega-side chain appendages of various prostacyclin and prostaglandin analogues, resulting in high (E)-selectivities for the C13-C14 double bond and leading to the total syntheses of isocarbacyclin, 15R-TIC, carbacyclin, and PGF(2 alpha) and the formal syntheses of 15-deoxy-TIC and PGJ(2).
