- One-Pot Palladium-Catalyzed Cross-Coupling Treble of Borylation, the Suzuki Reaction and Amination
-
A methodology for a sequential palladium-catalyzed cross-coupling procedure consisting of borylation, the Suzuki reaction and amination has been developed for the assembly of molecules with multi-aryl backbones. The linchpin of this development is the meta-terarylphosphine ligand, Cy*Phine, which has been employed as an air- and moisture-stable precatalyst, Pd(Cy*Phine)2Cl2, to improve the efficiency of one-pot borylation–Suzuki reactions. Additionally, the reactivity of the Pd-Cy*Phine system could be tuned to furnish a one-pot, borylation–Suzuki reaction–amination (BSA) cross-coupling treble. The methodology successfully integrated complementary conditions for three distinctly different and modular reactions. Average yields of 74–94% could be achieved for each segment that cumulatively afforded 50–84% yield over the entire three-step sequence in a single pot. (Figure presented.).
