摘要：
Urocanic acid undergoes photooxidative cleavage at the acrylic acid side chain to afford imidazole carboxaldehyde. The reaction is accelerated in the presence of purines. Evidence is presented that the photooxidation involves a reaction of the UA radical cation and ground state molecular oxygen.
