Directed ortho -Metalation–Cross-Coupling Strategies. One-Pot Suzuki Reaction to Biaryl and Heterobiaryl Sulfonamides

Résumé

A general synthesis of stable ortho-boropinacolato aryl and heteroaryl sulfonamides by directed ortho-metalation (DoM) and either MeOBPin or i-PrOBpin electrophile quench, 3 → 4, is described. A one-pot metalation–Suzuki cross-coupling procedure for the synthesis of biaryls and heterobiaryls, 3 → 5, and a complementary DoM–Ir-catalyzed boronation sequence (Scheme 6) are delineated.
