Resumo

The synthesis of bicyclic allyl acetate 2, a promising precursor of (-)-galileolactone 1, is described. The approach is based on the separation of diastereomeric carboxamides obtained by amidation of racemic gem-dichloro-substituted Grieco lactone with (+)-α-methylbenzylamine. Subsequent steps of transformation of an individual diastereomer include reactions of complete reductive dechlorination, construction of an allyl alcohol fragment in the ring part by stereo- and regiospecific bromohydroxylylation with NBS in aqueous THF, and dehydrobromination.
