benzoquinones, or sulfonylimines were found to couple with arynes and isocyanides, giving iminodihydroisobenzofuran or iminoisoindoline derivatives of structural diversity in a straightforward manner. Nucleophilic addition of isocyanides to arynes, a first step of the three-component coupling, was proved to be reversible by the reaction of an unsymmetrical aryne.
发现各种醛,酮,苯醌或磺酰亚胺与芳烃和异氰酸酯偶联,以直接的方式得到结构多样性的亚氨基二氢异苯并呋喃或亚氨基异吲哚啉衍生物。异氰酸酯向芳烃的亲核加成是三组分偶联的第一步,通过不对称芳烃的反应被证明是可逆的。
