Direct construction of biaryl-bridged 8–11 membered N-heterocycles via gold(i)-catalyzed intramolecular [4 + 2] benzannulation of N-tethered diynyl benzaldehydes

Abstract

An efficient method for the expeditious synthesis of the architecturally challenging biaryl-bridged 8–11 membered N-heterocycles that relies on gold(I)-catalyzed intramolecular [4 + 2] benzannulation of N-tethered diynyl benzaldehydes is described....
