α-Isocyanoacetamide derivatives were first converted to oxazolines under newly developed conditions. These oxazolines were used as precursors of α-isocyanoacrylamides, which could lead to various 2-arylated imidazolones. In addition, it was shown that both oxazolines and their precursors could efficiently lead to imidazolones unsubstituted at C2 in a very rapid, one-pot transformation, thus paving
在新开发的条件下,α-异氰基乙酰胺衍生物首先转化为恶唑啉。这些恶唑啉用作 α-异氰基丙烯酰胺的前体,可产生各种 2-芳基化咪唑酮。此外,恶唑啉及其前体都可以通过非常快速的一锅法转化有效地导致 C2 处未取代的咪唑酮类化合物,从而为通往咪唑酮类的前所未有的途径铺平了道路,对不同的取代模式具有良好的耐受性。
