A combined electron spin resonance (ESR) and density functional theory study has been carried out to obtain deeper insight in the reaction mechanism of the photorearrangement of 3-hydroxyindolic nitrones. Also, in this case, the combination of these

Amidinoquinoxaline N-oxides represent a novel family of heterocyclic spin traps. In this work, their ability to trap O- and C-centered radicals was tested using selected derivatives with different structural modifications. All the studied nitrones we

The 5-exo-dig cyclization of propargylic amides proceeds efficiently in the system CeCl3—NaI—I2 under microwave irradiation to afford polysubstituted oxazoles, e.g. (II) and (IV), in moderate to high yields.

Functionalized polysubstituted oxazoles are an important class of five-membered N,O-heterocycles that occur widely in the structure of natural products and fine chemicals. They are also often used as building blocks in the synthesis ofheterocyclic mo

The occurrence of unsaturated systems in natural products combined with the mildness and the wide range of applicability of CeCl(3) promoted methodologies suggest several potential future synthetic applications within the field of total synthesis of
