A new approach has been developed for the synthesis of linear α,β-unsaturated amides by the direct coupling of isocyanates with alkenylaluminum reagents. At room temperature, the desired α,β-unsaturated amides were isolated in good to excellent yields with good functional-group tolerance in the absence of any catalyst or additive.

从异氰酸酯和链烯基铝试剂合成线性 α,β-不饱和酰胺

通过异氰酸酯与链烯基铝试剂的直接偶联，开发了一种用于合成线性 α,β-不饱和酰胺的新方法。在室温下，在没有任何催化剂或添加剂的情况下，所需的 α,β-不饱和酰胺以良好的收率和良好的官能团耐受性分离出来。
