The putative aglycone of pseudopterosin GâJ and its enantiomer were synthesised enantiospecifically from 2,3-dimethoxytoluene and η3-allyl cationic complexes of molybdenum and iron respectively. The AâABâABC 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 tetrahydronaphthalene (â)-41a was determined
