Herein, we report a Pd-catalyzed aerobic lactamization of unactivated γ-C(sp3)–Hbonds of aliphaticcarboxylicacids and amino acids derivatives. The utilization of Pd(OAc)2 as a catalyst, along with catalytic AgNO2 as an electron transfer mediator, circumvents the need for stoichiometric oxidants and demonstrates significant practicality.
