抄録

Stereocontrolled total synthesis of toxic sesquiterpenoids of picrotoxane type, (-)-picrotoxinin (1) and (+)-coriamyrtin (2) is described. The double cyclization of a conjugated cyclohexenone 4 afforded the isotwistane compounds, 10a and 10b, which were converted into properly functionalzed cis-hydrindane derivative 17 via novel bridgehead hydroxylation of the bicyclo[3.2.1]octan-2-one moiety in the isotwistane intermediate 5. Optical resolution of 17 was made and the resulting (+)-17 was converted into a common and key intermediate (-)-6, from which (-)-picrotoxinin (1) and (+)-coriamyrtin (2) were synthesized.
