ChemInform Abstract: Methyl 2‐Benzoylamino‐3‐dimethylaminopropenoate in the Synthesis of Heterocyclic Systems. The Synthesis of Substituted 3‐Benzoylamino‐2H‐pyran‐2‐ones.

The behaviour of 4-alkoxy methylene-2-phenyl-4H-oxazol-5-one and 4-dimethyl amino methylene-2-phenyl-4H-oxazol-5-one toward nitrogen nucleophiles under microwave heating

“…Compound 5 reacts with ethyl acetoacetate to yield 16; under similar conditions 1 failed to react (Scheme 3). Compounds 16 was previously reported by Svete et al 12 from the reaction of ethyl 2-benzoyl-3-dimethylaminopropenoate with acetylacetone or ethyl acetoacetate.…”
