Water is demonstrated as a suitable solvent for NHC-catalyzed reactions of enals. The use of D2O as a solvent allows for the effective incorporation of deuterium isotopes into organic molecules.
activation of saturated acid chlorides by oxidative N-heterocycliccarbene catalysis has been successfully utilized to synthesize enantio-enriched spirooxindolelactones and δ-lactones. The reaction involves the transformation of the β sp3 carbon of saturated acid chlorides into an electrophilic carbon as a key step. The product was obtained in excellent yield and stereoselectivity.
