An efficient functionalization of ortho-C(sp2)–H bonds of picolinamide (PA)-protected benzylamine substrates with a range of vinyl iodides as well as acetylenic bromide is reported. ortho-Phenyl benzoic acid (oPBA) acts as an effective promoter in this reaction system. This method provides a practical strategy to access highly functionalized benzylamine compounds for organic synthesis.
据报道,吡啶甲酰胺(PA)保护的苄胺底物的邻位-C(sp 2)-H键与一系列乙烯基碘以及炔属溴化物的有效官能化作用。在该反应体系中,邻苯基苯甲酸(o PBA)充当有效的促进剂。该方法提供了一种实用的策略,可将高度官能化的苄胺化合物用于有机合成。
