Two intermediates in the reaction between dibenzoylacetylene and enol systems in the presence of triphenylphosphine in THF/H2O
摘要:
The reaction between dibenzoylacetylene and enol systems, such as acetylaceton or cyclohexane-1,3-dione in the presence of triphenylphosphine in THF/H2O, leads to 4-acetyl-3-benzoyl-1-phenyl-1,5-hexanedione and 2-hydroxy-3-(2-oxo-2-phenylethyl)-2-phenyl-3,5,6,7-tetrahydro-1-benzofuran-4(2H)-one. Subsequently, these compounds undergo cyclization and elimination reactions in acidic dichloromethane at room temperature to produce known highly functionalized furan derivatives.
