Chemo- and Regioselective Functionalization of Uracil Derivatives. Applications to the Synthesis of Oxypurinol and Emivirine
摘要:
A novel route for the synthesis of 4,5-difunctionalized uracils using a chemo-and regioselective bromine/magnesium exchange reaction on 5-bromo-4-halogeno-2,6-dimethoxypyrimidines has been developed. Applications to the synthesis of pharmaceuticals such as oxypurinol and emivirine are reported.
The invention is related to compounds of Formula (I), (II), or (III):
or a pharmaceutically acceptable salt, solvate, ester, and/or phosphonate thereof, compositions containing such compounds, and therapeutic methods that include the administration of such compounds.

Although the introduction of halogens into the pyrimidine ring has been accomplished numerous times, the methods usually involve either specialised reagents or very aggressive conditions. This communication paper describes the introduction of bromine into position 5 of the pyrimidine ring using common inorganic salts at room temperature. An evaluation of the substituents required for successful reaction
