3-(methylsulfanyl)-5-phenyl-4-isoxazolecarbonitriles and 5-aryl-3-(methylsulfanyl)-4-isoxazolecarbaldehyde oximes in good yields by varying the substratereagent stoichiometry and temperature of the reaction medium.
通过与羟胺盐酸盐反应,将2-芳基-3,3-双(烷基硫烷基)丙烯醛用于合成三种不同的异恶唑。我们合成了不同取代的异恶唑类化合物,如(芳基)[5-(甲基硫烷基)-4-异恶唑基]亚甲酮,3-(甲基硫烷基)-5-苯基-4-异恶唑甲腈和5-芳基-3-(甲基硫烷基)-4-异恶唑甲醛通过改变底物试剂的化学计量和反应介质的温度,可以得到良好的收率。
