The direct arylation of aliphaticaldehydes has been established via Pd-catalyzed sp3 C-H bond functionalization in the presence of 3-aminopropanoic acids as transient directing groups. The reaction showed excellent functional group compatibility and chemoselectivity in which a predominant preference for functionalizing unactivated β-C-H bonds of methyl groups over others was achieved.
