  摘要：

  N-tert-Butylamides are readily converted into the corresponding carboxylic acids by simple nitrosation. The process, which occurs under mild nonaqueous conditions, leaves carboxylic esters untouched and transforms multicomponent reaction products into useful building blocks for further synthetic elaboration.

  synthesis of Palomid 529, a drug in development for the treatment of glioblastoma and neovascular age-related macular degeneration. With a combination of experimental and theoretical methods, we get more insight into the essential issues of strategy determining the reaction process. The stronger coordinating ability of 2-aryloxypyridine and the less steric hindrance of amide are pivotal to the high chemoselectivity
