Synthetic routes to sixteen lipophilic lariat ether N-(X)sulfonyl carboxamides with X = trifluoromethyl, methyl, phenyl, and p-nitrophenyl are described. For this new family of proton-ionizable lariat ethers in which the acidity can be ‘tuned’ by X group variation, the ring size is systematically varied from 12-crown-4 to 14-crown-4 to 15-crown-5 to 18-crown-6.
描述了十六种亲脂性套索状醚N-(X)磺酰基羧酰胺的合成路线,其中X =三氟甲基,甲基,苯基和对硝基苯基。对于这个新的质子可电离的套索状醚族,其中的酸度可以通过X基团变化来“调节”,环的大小从12冠4到14冠4到15冠5到18有系统地变化。 -皇冠-6。
