5,6-Disubstituted 3-benzoylamino-2H-pyran-2-ones 3 are prepared either from 1.3-dicarbonyl compounds 1 and methyl 2-benzoyl-amino-3-dimethylaminopropenoate (2) in an one-step reaction or from ethyl 2-acyl-3-dimethylaminopropenoates 5a,b or 2-(dimethylamino)-methylene-1,3-diketones 5c,d and 5-oxo-2-phenyl-1,3-oxazole 6.
