Tandem reduction / intramolecular hydroxyalkylation of (3-hydroxyphenyl)alkanoates: a new regioselective approach to 1,8-dihydroxytetralins
摘要:
4-(3-hydroxyphenyl)-butanoates 4, on treatment with DIBALH, followed by hydrolytic work-up, undergo a novel completely regioselective intramolecular hydroxyalkylation reaction to give 1,8-dihydroxytetralins. The yield of the reaction depends heavily on the structure of starting material, best results being achieved with 3,3-disubstituted butanoates.
