A mild activation of N-(phenylselenomethyl)phthalimide by iodonium ion in the presence of alcohols to give the corresponding O-phthalimidomethyl derivatives (Pim-ethers) is provided. Simple cleavage of the phthalimido group with ethylenediamine is also reported thus making this approach a new and efficient method of protecting alcohols.
提供了在醇存在下通过碘离子对N-(苯基硒代甲基)邻苯二甲酰亚胺的轻度活化,从而得到相应的O-邻苯二甲酰亚胺基甲基衍生物(Pim-醚)。还报道了用乙二胺简单裂解邻苯二甲酰亚胺基,因此使该方法成为保护醇的新的有效方法。
