Dedicated to the memory of Prof. Jean F. Normant
A variety of highly functionalized β-hydroxynaphthoate derivatives are prepared by
a two-step protocol: (1) acyl-alkylation of benzynes with ketodioxinones and (2) intramolecular
aldol condensation. The substitution pattern of the products is related to polycyclic
natural products derived from the type-II polyketide biosynthesis.
Key words
ketodioxinones - benzynes - acyl-alkylation - aldol condensation - cascade reaction
