A two-step metal–halogen exchange and diastereoselective copper-mediated Michael addition onto a complex α,β-unsaturated system has been developed and applied toward the synthesis of bisaryl Nrf2 activators. Optimization of metal–halogen exchange using (n-Bu)3MgLi allowed for the preparation of custom aryl-functionalized magnesiate reagents at noncryogenic temperatures. Following transmetalation, these
已经开发了两步金属-卤素交换和非对映选择性铜介导的迈克尔加成到复杂的α,β-不饱和系统上,并将其应用于双芳基Nrf2活化剂的合成。使用(n -Bu )3 MgLi优化金属-卤素交换可在非低温条件下制备定制的芳基官能化氧化镁试剂。在金属转移之后,将这些试剂用于高度非对映选择性的迈克尔加成反应中。
