Stereospecific nitromethane coniugate addition to 4-oxygenated-2-substituted cyclopent-2-enones: A simple approach to prostaglandins.
The compatibility of nitromethane conjugate addition to 2-cyclopentenones bearing a 4-oxygenated funtion has been illustrated trough a short and proctical sunthesis of Corey aldehyde. A new synthesis of PGF2a featuring the introduction of the omega-chain via [3+2] cycloaddition has been described
