An efficient procedure was developed for the synthesis of previously unknown 3-aryl(styryl)-2-(4-arylthiazol-2-yl)oxirane-2-carboxamides and 2-(4-arylthiazol-2-yl)-1-oxaspiro[2.5]octane-2-carboxamides based on treatment of (E)-3-aryl-2-(4-arylthiazol-2-yl)acrylonitriles and cyclohexylidene(4-arylthiazol-2-yl)acetonitriles with an H2O2—KOH system in EtOH. Oxidation of (E)-3-(4-chlorophenyl)-2-(4-ph
开发了一种有效的方法来合成以前未知的 3-芳基(苯乙烯基)-2-(4-芳基噻唑-2-基)环氧乙烷-2-甲酰胺和 2-(4-芳基噻唑-2-基)-1-oxaspiro [2.5]基于用H2O2-KOH系统处理(E)-3-芳基-2-(4-芳基噻唑-2-基)丙烯腈和环己叉(4-芳基噻唑-2-基)乙腈的[2.5]辛烷-2-甲酰胺在乙醇中。(E)-3-(4-氯苯基)-2-(4-苯基噻唑-2-基)丙烯腈用 H2O2-AcOH 系统氧化得到 3-(4-氯苯基)-2-(4-苯基噻唑-2- yl)oxirane-2-carbonitrile,产率为 55%。
