Synthesis of (-)-nakamurol A and assignment of absolute configuration of diterpenoid (+)-nakamurol A

The total synthesis of the enantiomer of the marine sponge diterpenoid nakamurol A and determination of the absolute configuration of this natural product are reported. This first synthetic entry to thelepogane-type diterpenoids involves the use of the bi
