Two different approaches were investigated in order to prepare the title compound 2; best results were obtained when the tandem reduction/intramolecular hydroxyalkylation of the appropriate 5-alkoxy-(3-hydroxyphenyl)pentanoate was performed on an ester of chemoenzymatic origin, already bearing the two chiral centers present in 2 with the correct relative and absolute stereochemistry.
