Several π-deficient 2-(arylsulfonyl)ethyl groups have been studied as carboxylic acid protecting groups. The 2-[3,5-bis(trifluoromethyl)phenylsulfonyl]ethyl group is the most easily removed protecting group for acids under mild basic conditions using aqueous NaHCO 3 .
已经研究了几种 π 缺陷型 2-(芳基磺酰基)乙基作为羧酸保护基团。2-[3,5-双(三氟甲基)苯磺酰基]乙基是在温和碱性条件下使用 NaHCO 3 水溶液最容易去除的酸保护基团。
