Overall brevity in the synthesis of the title compounds (see scheme) is achieved by a sequential electrophilic aromatic substitution of indole and a regio‐ and diastereoselective intermolecular Diels–Alder cycloaddition to establish the key precursor—a neopentyl chloride. A stereoselective Ritter reaction and dehydration are used for the installation of the isonitrile unit.
一种常见的方法:标题化合物的合成(参见方案)的总体简洁性是通过吲哚的顺序亲电芳香取代和区域选择性和非对映选择性分子间 Diels-Alder 环加成反应来实现的,以建立关键前体——新戊基氯。立体选择性 Ritter 反应和脱水用于安装异腈装置。
