An enantioselective rhodium‐catalyzed 1,2‐addition of heteroarylboronates to aryl N‐tosylimines and N‐nosylimines has been developed. Our chiral rhodium‐diene catalyst showed high efficiency in the stereochemical control of this reaction. Under the optimal reaction conditions, a variety of boronates bearing pyridinyl, furyl or thienyl groups were successfully reacted with aryl imines. The boronate
已经开发了对映体选择性的铑催化的杂芳基硼酸酯的1,2-加成到芳基N-甲苯胺和N- nosylimines中。我们的手性铑二烯催化剂在该反应的立体化学控制中显示出高效率。在最佳反应条件下,各种带有吡啶基,呋喃基或噻吩基的硼酸酯已成功地与芳基亚胺反应。具有稳定性和反应性平衡的硼酸酯类型对于在该反应中获得高反应产率至关重要。
