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

[GRAPHICS] 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.
