Thermal Cycloaddition of Aroylketene to 1-Aryl-1-trimethylsilyloxyethylene: A Simple Synthesis of 2,6-Diaryl-4H-pyran-4-one
摘要:
Aroylketene (2) generated by pyrolytic decarbonylation of 5-aryl-2,3-dihydro-2,3-furandione (1) reacted with 1-aryl-1-trimethylsilyloxyethylene (3) in a regioselective manner to give 2,6-diaryl-4H-pyran-4-one (5) and/or 1,5-diarylpentane-1,3,5-trione (6). This reaction provides a simple synthetic method of 2,6-diaryl-4H-pyran-4-one with various substituents in the aryl group.
