Selective Palladium-Catalyzed Direct Arylation of Furo[3,2-<i>b</i>]pyridines
A method for palladium-catalyzeddirectarylation has been developed for the selective functionalization of the C-3 and C-7 positions of 2-substituted furo[3,2-b]pyridines. An unconventional reactivity resulting from the annulation of a pyridine ring with a furan ring is outlined and results in an unprecedented C-7H bond activation. The role of the pivalic acid additive is rationalized by invoking
已经开发了一种用于钯催化的直接芳基化的方法,用于将2-取代的呋喃[3,2- b ]吡啶的C-3和C-7位置选择性官能化。概述了由吡啶环与呋喃环环合引起的非常规反应性,并导致前所未有的C-7H键活化。新戊酸添加剂的作用可通过对两个芳基化调用一致的金属化-去质子化途径(CMD)来合理化。
