An Efficient Approach to Optically Active Benzoprostacyclins by a Two-component Coupling Process

A highly efficient and practical synthesis of enantiomerically pure benzoprostacyclins, chemically stable and therapeutically useful prostaglandin I2 analogues, is developed which includes an efficient preparation of 2--4-siloxycyclopent-2-en-1-one 3 in optically active form and the conjugate addition of ω side-chains onto 3 followed by cyclization to the key intermediate (1R,2R,3'S)-2-endo-siloxy-1-exo-(3'-siloxyalk-1-enyl)-3a,8b-cis-2,3,3a,8b-tetrahydro-1H-5-bromocyclopentabenzofuran 4.
