Palladium(II)-Mediated Cascade Carbonylative Annulation of o-Alkynyl-phenols on Silyl Linker-Based Macrobeads: A Combinatorial Synthesis of a 2,3-Disubstituted Benzo[b]furan Library

摘要

A palladium(II)-mediated cascade carbonylative annulation of o-alkynylphenols was achieved successfully on silyl linker-based macrobeads, which led to an efficient combinatorial synthesis of a 2,3-disubstituted benzo[b]furan library.
