Molecular-Iodine-Catalyzed Cyclization of 2-Alkynylanilines via Iodocyclization–Protodeiodination Sequence
摘要:
Molecular iodine catalyzes a cyclization of N-ary1-2-alkynylanilines, which proceeds through the iodocyclization of 2-alkynylanilines followed by the protodeiodination of the iodocyclized intermediates at room temperature. Furthermore, the molecular iodine catalysis can be applied to the cascade cyclization of 2-(enynyl)aniline and to the tandem cyclization addition reaction of 2-alkynylanilines with alpha,beta-enones.
