Novel organic photoCORMs based on micelle-encapsulated unsaturated cyclic α-diketones were designed and synthesized. These photoCORMs can be activated by visible light, have potentially low toxicity, allow the delivery of carbon monoxide to be monitored by fluorescence imaging techniques, and thus are useful tools for the study of the biological function of CO.
[reaction: see text] A simple, high-yielding synthesis of 2,4,5-trisubstituted imidazoles from 1,2-diketones and aldehydes in the presence of NH(4)OAc is described. Under microwave irradiation, alkyl-, aryl-, and heteroaryl-substituted imidazoles are formed in yields ranging from 80 to 99%. Short syntheses of lepidiline B and trifenagrel illustrate the utility of this approach.
