The synthesis of racemic Δ12,14-15-deoxy-PG-J1 is readily achieved in six steps employing as the key transformation a one-pot conjugate addition–Peterson olefination sequence using exo-2-trimethylsilyl-3a,4,7,7a-tetrahydro-4,7-methanoinden-1-one. Additionally a Noyori-type three-component coupling approach is employed for the synthesis of enantioenriched epi-Δ12-15-deoxy-PG-J1 from 4(S)-tert-butyl
