NHC-catalysed Reaction of Carboxylic Anhydrides

Recently, the Ye group developed the NHC-catalysed enantioselective [3 + 2] cyclocondensation of in situ activated cx,p-unsaturated carboxylic acids with 

Very recently, the first highly efficient enantioselective NHC-catalysed annulation reaction for the synthesis of dihydroquinolones with carhojq lic acids was reported by the Scheidt group. In addition, the utilisation of
