Halocarbon Chemistry. 3. Ortho Metallation-Induced Cyclization of Acetylenes: One-Flask Synthesis of 2,3-Disubstituted Benzofurans, Thianaphthenes, and Indoles
Johnson, Francis,Subramanian, Raghupathi
, p. 5040 - 5041 (1986)
A new base-induced cyclization is described which involves the direct one-pot conversion of trifluoroethyl phenyl ethers, thioethers, and amines, in the presence of 4 equiv of alkyl- or aryllithium reagents, to 2,3-disubstituted benzofurans, thianaphthene
In-Depth Assessment of the Palladium-Catalyzed Fluorination of Five-Membered Heteroaryl Bromides
Milner, Phillip J.,Yang, Yang,Buchwald, Stephen L.
, p. 4775 - 4780 (2015/10/28)
A thorough investigation of the challenging Pd-catalyzed fluorination of five-membered heteroaryl bromides is presented. Crystallographic studies and density functional theory (DFT) calculations suggest that the challenging step of this transformation is
