摘要
Iterative cross-coupling is a highly efficient and versatile strategy for modular construction in organic synthesis, though this has historically been demonstrated solely in the context of C-C bond formation. A C-N cross-coupling of haloarene methyliminodiacetic acid (MIDA) boronates with a wide range of aromatic and aliphatic amines is reported. Successful cross-coupling of aliphatic amines was realized only through protective enolization of the MIDA group. This reaction paradigm was subsequently utilized to achieve a one-pot C-N/C-C cross-coupling sequence.
