A new straightforward entry into unsaturated nine-membered lactams of potential use as external reverse turn inducers was developed. It is based on an Ugi multicomponent reaction using two unsaturated substrates, followed by highly stereoselective ring-closing metathesis (RCM). The synthesis of a nine-membered secondary lactam by RCM is reported for the first time.
已经开发出一种新的直接进入不饱和九元内酰胺的方法,该内酰胺可能用作外部反向转导诱导剂。它基于使用两个不饱和底物的Ugi多组分反应,然后进行高度立体选择性的闭环复分解(RCM)。首次报道了通过RCM合成九元仲内酰胺。
