of pentadienylindium to unsaturated aldehydes afforded the alcohols 7, from 1,2-addition, substituted with a 1,4-diene unit. Subsequent anionic oxy-Cope rearrangement provided the Michael 1,4-addition product 8. Wittig reaction followed by intramolecular [2+4] cycloaddition afforded the hydrindane skeleton in an enantioselective manner (five steps).
