A related series of bisamides have been evaluated for rational correlation between anion complexation and organocatalysis: remarkable enhancement of hydrogen bonding to anions was observed along with significant increases in catalytic activity in the Baylis–Hillman reaction. In addition, X-ray crystallography showed a large degree of pre-organisation was observed in one receptor by incorporation of
