A new three‐component reductive arylation of amides with stable reactants (iPrOH and arylboronate esters), making use of a 2‐pyridinyl (Py) directing group, is described. The N‐Py‐amide substrates are readily prepared from carboxylic acids and PyNH2, and the resulting N‐Py‐1‐arylalkanamine reaction products are easily transformed into the corresponding chlorides by substitution of the HN‐Py group with
描述了一种新的酰胺与稳定反应物的三组分还原芳基化反应(iPrOH和芳基硼酸酯),利用2-吡啶基(Py)导向基团。N-Py-酰胺底物可以很容易地由羧酸和PyNH 2制备,所得的N-Py-1-芳基烷胺反应产物很容易通过用HCl取代HN-Py基团而转化为相应的氯化物。1-芳基-1-氯代烷烃产品可进行取代和交叉偶联反应。因此,获得了将羧酸转化成各种官能团的通用方案。Py‐NH 2副产物可以回收利用。
