A series of 4-(3-hydroxyphenyl)butanoates 3 has been prepared and transformed into 1,8-dihydroxytetralins of general formula 2 by treatment with 2 equivalents of DIBALH followed by quenching with aqueous NH4Cl. A possible mechanism for this novel totally regioselective intramolecular hydroxyalkylation is suggested and the factors affecting the stability of 1,8-dihydroxytetralins 2 are also discussed. © 1994.
