Cross metathesis as a general strategy for the synthesis of prostacyclin and prostaglandin analogues

[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).
