Catalytic asymmetricsynthesis of axiallychiral o‐iodoanilides and o‐tert‐butylanilides as useful chiral building blocks was achieved by means of binaphthyl‐modified chiral quaternary ammonium‐salt‐catalyzed N‐alkylations under phase‐transfer conditions. The synthetic utility of axiallychiral products was demonstrated in various transformations. For example, axiallychiral N‐allyl‐o‐iodoanilide was

evaluated primarily for in vitro efficacy against Gram-positive and Gram-negative bacteria, commonly responsible for nosocomial and community acquired infections. In addition, we also assessed the activity of these compounds againstMycobacteriumtuberculosis (Tuberculosis) and Plasmodium spp. (Malaria). This led to the discovery of highly potent compounds active against bacterial pathogens and malaria parasites

The N-heterocyclic carbene (NHC)-catalyzed enantioselectivekineticresolution of anilides (a kind of hemiaminals) is reported. Upon exposure to the reaction in the presence of an NHC precatalyst and base, catalytic C–O bond formation occurs, providing axially chiral isoindolinones in high yields with excellent enantioselectivities.
