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
已经评估了一系列相关双酰胺的阴离子络合和有机催化之间的合理相关性:观察到氢键与阴离子的显着增强以及 Baylis-Hillman 反应中催化活性的显着增加。此外,X 射线晶体学表明,通过结合双(三氟甲基)苯胺基团和硫代酰胺官能团,在一个受体中观察到了很大程度的预组织。该系列中的新型双功能酰胺/N-酰基磺酰胺具有最佳催化性能。
