Experiments on the synthesis of tetracycline. Part 15. Oxidation of phenols and ring A model phenols to o-hydroxy-dienones with benzeneseleninic anhydride

Abstract

Benzeneseleninic anhydride has been used to oxidise simple alkylphenols and tetracycline ring A model phenols to hydroxy-dienones. The corresponding phenolate salts with benzeneseleninic anhydride give increased yields of o-hydroxylated products
