Reagent Design and Ligand Evolution for the Development of a Mild Copper-Catalyzed Hydroxylation Reaction

Parallel synthesis and mass-directed purification of a modular ligand library, high-throughput experimentation, and rational ligand evolution have led to a novel copper catalyst for the synthesis of phenols with a traceless hydroxide surrogate. The mild reaction conditions reported here enable the late-stage synthesis of numerous complex, druglike phenols.

Five-Membered 2,3-Dioxo Heterocycles. XL. Reaction of 3-Aroyl-1,2-dihydro-4H-pyrrolobenzoxazine-1,2,4-triones with o-Phenylenediamine

3-Aroyl-1,2-dihydro-4H-pyrrolobenzoxazine-1,2,4-triones react with o-phenylenediamine with formation of (Z)-N-o-hydroxyphenyl-4-aryl-2,4-dioxo-3-(2-oxo-1,2,3,4-tetrahydroquinoxalin-3-ylidene)butananilides whose aminolysis yields (Z)-3-phenacylidene-1,2,3,4-tetrahydroquinoxalin-2-ones and N-o-hydroxyphenyloxamides.
