New α,β-unsaturated valerolactams showing potential as Michael acceptors were synthesized from heterocyclic imines as starting materials. The synthetic procedure is based on an acid chloride addition in the first step, followed by a modified Hosomi-Sakurai reaction, and a final ring-closing metathesis using a ruthenium catalyst. heterocycles - imines - unsaturated lactams - Michael acceptor - ring-closing
以杂环亚胺为起始原料合成了新的α,β-不饱和戊内酰胺,它们具有作为迈克尔受体的潜力。合成程序的第一步是在第一步中添加酰氯,然后进行修饰的细森樱井反应,最后使用钌催化剂进行闭环复分解反应。 杂环-亚胺-不饱和内酰胺-迈克尔受体-闭环复分解
