摘要
The putative aglycone of pseudopterosin G-J and its enantiomer were synthesised enantio specifically from 2,3-dimethoxytoluene and eta (3)-allyl cationic complexes of molybdenum and iron respectively. The A --> AB --> ABC annulation strategy entailed the use of allyl cations or their equivalents for the creation of the three benzylic stereogenic centres. The X-ray structure of tetrahydro naphthalene (-)-41a was determined.
