The products obtained from the lead tetraacetate (LTA) oxidation of N-acylbenzylidene isoquinoline enamides are a function of the type of carbonyl function in the enamide, the solvent, and the type of substitution on the benzylidene aromatic ring. The benzoyl enamides yield 2-P-acetoxy-substituted enamides. The ethoxycarbonyl enamides, containing electron-releasing substituents on the benzylidene ring, efficiently form ...
