摘要
A regioselective synthesis of 2,6-diarylpyridines through base (sodium hydroxide in DMSO) catalyzed ring transformation of suitably functionalized 2H-pyran-2-ones with benzamide has been delineated. However, similar reaction of 2H-pyran-2-ones with benzamide using sodium hydroxide in absolute ethanol yielded highly congested delta keto esters with an active methylene centre, instead of 2,6-diarylpyridines.
