Ultrasound-assisted Synthesis of Azlactone and its Reactions with Nucleophiles
摘要:
4-(2-Oxoindolin-3-ylidene)-2-phenyl-5(4H)-oxazolone (azlactone) was synthesized as a mixture of E- and Z-isomers by ultrasound-assisted Erlenmeyer-Plochl reaction between isatin and N-benzoylglycine. Treatment of azlactone with nucleophiles causes opening of its oxazolone moiety.
