Palladium-Catalyzed Suzuki-Miyaura Cross-Coupling Reactions of Enantiomerically Enriched Potassium β-Trifluoroboratoamides with Various Aryl- and Hetaryl Chlorides.
Summary of "Palladium-Catalyzed Suzuki-Miyaura Cross-Coupling Reactions of Enantiomerically Enriched Potassium β-Trifluoroboratoamides with Various Aryl- and Hetaryl Chlorides."
Enantiomerically enriched potassium β-trifluoroboratoamides were synthesized as air-stable solids in greater than 95:5 dr using pseudoephedrine as the chiral auxiliary. With these chiral nucleophiles, Suzuki-Miyaura cross-coupling reactions were carried out with various aryl- and hetaryl chlorides in good to excellent yields. Moreover, the diastereoselectivities were preserved throughout the Suzuki-Miyaura cross-coupling reactions.
