Substituted 2-methylbenzofurans were obtained from 2-allylphenols via Pd2+-catalyzed oxidative cyclization using Cu(OAc)(2)LiCl as a reoxidant and wet DMF as a solvent. (C) 1998 Elsevier Science S.A. All rights reserved.
Enantio‐ and Diastereoselective, Complete Hydrogenation of Benzofurans by Cascade Catalysis
We report an enantio- and diastereoselective, complete hydrogenation of multiply substituted benzofurans in a one-pot cascade catalysis. The developed protocol facilitates the controlled installation of up to six new defined stereocenters and produces architecturally complex octahydrobenzofurans, prevalent in many bioactive molecules. A unique match of a chiral homogeneous ruthenium-N-heterocyclic
