The issue of the obtaining of complex tautomeric mixtures of 4‐mono‐substituted isoxazol‐5‐ones has been overcome by the use of entrapping reactants in a one‐pot protocols of Michael reactions with arylideneisoxazol‐5‐ones. Asymmetric three components Michael/electrophilic tautomer‐entrapping and four‐component Knoevenagel/Michael/electrophilic‐tautomer‐entrapping methodologies have been developed
通过在迈克尔反应与芳基间二
恶唑-5-
酮的一锅法中使用截留反应物,克服了获得4-单取代
异恶唑-5
酮的复杂互变异构混合物的问题。已经开发了不对称的三组分迈克尔/亲电子互变异构诱捕方法和四组分Knoevenagel /迈克尔/亲电子互变异构体捕获方法。
