frontier in the development of chiral stationary phases for chromatographic enantioseparation involves homochiral metal–organic frameworks (MOFs). Using enantiopure (R)-2,2′-dihydroxy-1,1′-binaphthalene-6,6′-dicarboxylic acid as a starting material, we prepared three homochiral MOFs that were further used as chiral stationary phases for high-performanceliquidchromatography to separate the enantiomers

are found in many biologically active natural products and pharmaceuticals, including important classes of antibiotics. Methods for the asymmetric synthesis of these molecules are therefore highly desirable, particularly through the selective functionalization of unreactive aliphatic C–H bonds. Here we show the development of a strategy for the asymmetric synthesis of β-, γ- and δ-lactams via the haemoprotein-catalysed
