One-Pot Preparation of 1-Acyl-1-methoxycarbonyloxiranes and 1-Acyl-1-cyanooxiranes from Methyl 3-Hydroxy-2-methylenealkanoates or 3-Aryl-3-hydroxy-2-methylenepropanenitriles

The reaction of sodium hypochlorite with methyl 3-hydroxy-2methylenealkanoates or 3-aryl-3-hydroxy-2-methylenepropanenitriles, dispersed on silica gel, in acetonitrile leads to oxidation of the alcohol function and epoxidation of the methylene group to give 2,2-disubstituted oxiranes in good yield.
次氯酸钠与甲基3-羟基-2-亚甲基烷酸酯或3-芳基-3-羟基-2-亚甲基丙腈在硅胶上分散,并在乙腈中反应,导致醇功能被氧化,亚甲基被环氧化,从而以良好产率得到2,2-二取代的环氧乙烷。
