The palladium catalyzed coupling of (S)-E-1 -tributylstannyl-1 -octen-3-01 (3) with 2-(6 carbethoxyhexyl)-3-iodo-2-cyclopenten-I-one gave a 70% yield of the (S)-ethyl ester of PGBI. Coriolic acid was synthesized in 75% yield by coupling 3 with Z-lo-iododecenoic acid, demonstrating the tolerance of t
