Synthesis of (+)-Taxodione

A stereoselective synthesis of (+)-taxodione (1) starting from (-)-abietic acid (2) via the ironcarbonyl complex 4 is described.Conversion of the carboxyl function of 4 into a methyl group via 5 and 6 proceeds in excellent overall yield.The next steps are the introduction of oxygen functions in the positions 12 and 6.Oxidation with BSA yields the quinonemethide 1.The 1H- and 13C-NMR resonances of all compounds have been assigned.

SYNTHESIS OF (+)-TAXODIONE FROM (-)-ABIETIC ACID

A new stereoselective synthesis of (+)-taxodione (1) from (-)-abietic acid (2) via the iron carbonyl complex 3 is described.
