摘要
The reaction of 5-iodo-1,3-dioxin-4-ones with trifluoromethyl iodide in the presence of copper power in hexamethylphosphoric triamide affords the title compounds, which can be converted either to alpha-trifluoromethylated beta-keto acid derivatives or to uracil or oxazine derivatives bearing a trifluoromethyl group.
