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

Enantioselective N-acylation of 4-aryl-beta-lactams in the presence of acyl transfer catalyst CI-PIQ provides an effective method for their nonenzymatic kinetic resolution.
