Efficient synthesis of 1-Benzyloxyphenyl-3-phenylacetones

1-[(Benzyloxy)phenyl]-3-phenylacetones 1a-c have been conveniently synthesized by acylation of the PhCH2Li-DABCO complex with their respective N-methyl O-methyl hydroxamates 5a-c. In four steps, ketones 1a-c having ortho-, meta- and para-benzyloxy substituents were obtained in 42-51% overall yields from commercially available 2-(hydroxyphenyl)acetic acids.

Regioselective synthesis of 1,8-dihydroxytetralins through a tandem reduction/intramolecular hydroxyalkylation of 4-(3-hydroxyphenyl)alkanoates

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.
