Abstract

2-Aryl-3-alkylindoles were prepared on solid phase via palladium-mediated heteroannulation of 1-alkyl-2-(trimethylsilyl) acetylene with amide resin-bound o-iodoaniline 1, followed by transformation of trimethylsilyl to iodide and then Suzuki coupling reactions. Traceless synthesis of symmetrical and unsymmetrical 2, 3-diarylindoles was achieved via palladium-mediated one-pot coupling/intramolecular indole cyclization of aryl-substituted ...
