  Palladium-Catalyzed Benzylic C–H Arylation of Azaarylmethylamines

  摘要：

  A direct C-H functionalization approach to produce aryl(azaaryl)methylamines from azaarylmethylamines without directing groups is described. Under conditions where the azaarylmethylamines' C-H is reversibly deprotonated, a Pd(OAc)(2)/NIXANTPHOS-based catalyst couples the resulting carbanions with various aryl halides to provide aryl-(azaaryl)methylamines This umpolung strategy directly provides tertiary amines without protecting or activating groups.

  A Petasis reaction of 2-pyridinecarbaldehydes with various amines and 4-substituted 1,2-oxaborol-2(5H)-ols was developed. In the presence of HCl, the reaction proceeded smoothly under very mild conditions and the corresponding desired products were obtained in medium to excellent yields. This method allows the access a wide range of highly functionalized allylic alcohols, which might be useful compounds

  A nickel‐catalyzed coupling of azaarylmethylamines with aryl chlorides has been achieved. NIXANTPHOS together with low cost NiBr2 was successfully developed and optimized to exhibit high reactivity at 2.5 mol % loading. Under optimized reaction conditions, aryl(azaaryl)methylamine products were afforded in good to excellent yields (22 examples, up to 98% yield).

  已经实现了镍催化的氮杂芳基甲胺与芳基氯化物的偶联。NIXANTPHOS与低成本NiBr 2一起成功开发并优化，以在2.5 mol％的装载量下表现出高反应活性。在优化的反应条件下，芳基（氮杂芳基）甲胺产品的收率好至极佳（22个实例，最高收率98％）。
