mediate the 6-endo-dig cyclization of (2-alkynyl)arylaldimines, generated in situ from (2-alkynyl)arylaldehydes and primary amines, has been developed via formal insertion of C═N and C≡C bonds into a C–Cl bond under catalyst-free conditions, providing convenient access to a range of structurally diverse polychlorinated 1,2-dihydroisoquinolines and heteroarene-fused nitrogen heterocycles.
通过正式插入C═N和C≡,已经开发出前所未有的四氯化碳用于介导由(2-炔基)芳基醛和伯胺原位生成的(2-炔基)芳基醛亚胺的6-内-挖-环化的方法。在无催化剂的条件下,C键变为C–Cl键,可方便地获得各种结构多样的多氯代1,2-二氢异喹啉和杂芳烃稠合的氮杂环。
