We report herein the first general catalytic system for the direct synthesis of N‐substituted γ‐ and δ‐lactams by reductive amination/cyclization of keto acids (including levulinic acid) with nitriles and H2 under mild conditions (7 bar H2, 110 °C, solvent free). The most effective catalyst, Pt and MoOx co‐loaded TiO2 (Pt‐MoOx/TiO2), shows a wide substrate scope, high turnover number (TON), and good reusability.
