An Unprecedented Tandem Annulation of ω-Azido-1-alkynes with Diaryliodonium Salts: A Facile Synthesis of Polycyclic Quinolines
摘要:
Polysubstituted quinolines are synthesized through an unprecedented cascade annulation of -azido-1-alkynes with diaryliodonium salts, which serve as C2-building blocks. The reaction proceeds smoothly and is catalyzed by Cu(I) catalysts to give various quinolines in good isolated yields with simple operation under mild conditions.

diaryliodonium triflates have been synthesized from both electron-deficient and electron-rich arenes and aryl iodides with mCPBA and triflic acid. A thorough investigation of the optimization, scope and limitations has resulted in an improved one-pot protocol that is fast, high-yielding, and operationally simple. The reaction has been extended to the direct synthesis of symmetrical iodonium salts from
