Synthesis of the A,B,C-ring system of hexacyclinic acid

(Chemical Equation Presented) The synthesis of the A,B,C-ring system (2) of hexacyclinic acid (1) is achieved starting from a selective Diels-Alder reaction followed by vinyl cuprate addition. The diastereoselective reduction of the ketone carbonyl at C16
