salts 10 are easily obtained by simple addition of hydroxylamine compounds 2 to substituted allenes 3 and 6 or to propargylphosphonium salt 9. These oximo derivatives are used for the synthesis of α,β-unsaturated oximes 1, and isoxazole derivatives 13.
通过将羟胺化合物2简单地添加到取代的烯丙基3和6或炔丙基phosph盐9上,可以容易地获得衍生自氧化膦5,膦酸酯8和phospho盐10的β-官能化肟。这些肟衍生物用于合成α,β-不饱和肟1和异恶唑衍生物13。
