ABSTRACT:
Enol ester precursors of benzoyl-1,3-cycloalkyldiones (e.g., the enol ester precursors of 2-(2'-nitrobenzoyl)-1,3-cyclohexanedione compounds) are converted to the desired benzoyl-1,3-cycloalkyldiones by heating the precursor in the presence of base and a catalytic amount of a trialkylsilylcyanohydrin as a cyanide source.
