A Versatile Method for Suzuki Cross‐Coupling Reactions of Nitrogen Heterocycles
A wide-ranging study of Suzuki reactions which use nitrogen-containing heterocycles is described (see scheme; dba=dibenzylideneacetone, Cy=cyclohexyl). This method is highly versatile (a single procedure was used for all substrates, including boronate esters and trifluoroborates), compatible with a variety of unprotected functionalities (e.g., NH2- and OH-substituted substrates), and efficient even with unactivated aryl chlorides.
