, p. 3459 - 3465 (2007/10/03)
Cyanoesters epoxides 1, when treated with o-phenylenediamine in presence or absence of hydrogen chloride, at reflux of acetonitrile, give the 2- alkoxycarbonyl-3-aryl-3,4-dihydro quinoxalines and 2-alkoxy carbonyl-3-aryl quinoxalines in good yields.

Regioselective ring opening of 3-aryl-2-cyano 2-(methoxy and ethoxycarbonyl) oxiranes 1 with chlorhydric acids gave halohydrins 3 with OH, CN and CO2Me or CO2Et on the same carbon atom. - Keywords: oxirane; β-chloro-α-cyano-α-hydroxyester; ketoester; regi
Short and efficient synthesis of new α-oximino esters
Boukhris, Said,Souizi, Abdelaziz,Robert, Albert
, p. 4693 - 4696 (2007/10/03)
α-Cyano α-alkoxy carbonyl epoxides 1 react, in refluxing alcohol, with hydroxylamine hydrochloride 2 in a direct ring opening reaction to give β-alkoxy α-oximino esters 4 in good yields. We have shown that this reaction proceeds through the formation of c
