A few model systems for CAO chemistry, which are catalytic, have been reported. Suzuki, Kawamoto, and co-workers synthesized and characterized Cu(II) complex with 2,2 -bipyridine (bpy) and a tyrosine derivative, 2,4,5-trihydroxy-phenylalanine (topa) (109). The resulting complex, [Cu(DL-topa)(bpy)]+, catalyzes the aqueous aerobic oxidation of benzylamine to benzaldehyde. There is a rate improvement of up to 4 compared to topa itself (109,110). However, polymerization of the topa moiety occurred during the oxidation reaction with loss of activity of the Cu(II) catalyst (109). 

Obtained by reaction of acetonitrile with 2,4,6-trihydroxy-benzaldehyde (Houben-Hoesch reaction) [6298]. 

Obtained by reaction of methyl iodide with 2,4,6-trihydroxy-3-( 1 -oxoethyl)benzaldehyde in the presence of potassium hydroxide in methanol at 70° (50%) [6330,6331,6332].
