Kharasch-Sosnovsky reaction, the oxidation of oxazolines and thiazolines bearing a variety of 2-alkyl substituents (chiral and achiral) were smoothly oxidized to their corresponding oxazoles and thiazoles, respectively. The key feature involved in the successful implementation of this important oxidation was the use of a mixture of Cu(I) and Cu(II) salts to enhance the oxidation of the intermediate captodative

relationship studies directed toward the use of mGluR5antagonists in the treatment of drug abuse, we sought a convenient means for gaining access to the oxazole analogues of MTEP. Toward this end, the aldehyde group in 2-methyloxazole-4-carboxaldehyde was successfully converted to a trimethylsilylethynyl group via the preparation of a dibromoolefin, conversion to acetylide using NaHMDS and MeLi, and trapping

The use of bromotrichloromethane-DBU is described for the selective oxidative conversion of several dihydro-heterocyclic systems to the corresponding heteroaromatics. Oxidative dehydrogenations to afford 4-hydroxy-2-pyridinones are examined under a variety of conditions. Studies of phenylselenenylation and peracid oxidation provide the novel spirocyclic oxirane .
