Synthesis of substituted uracils by the reactions of halouracils with selenium, sulfur, oxygen and nitrogen nucleophiles under focused microwave irradiation
Undermicrowaveirradiation, the nucleophilic substitutionreactions of halouracils with selenium, sulfur, oxygen and nitrogen nucleophiles was complete within several minutes with yields up to 99%. The method using microwaveirradiation is superior to those conducted under conventional heating processes.
