  Preparation and reaction of 4-methoxybenzyl (MPM) and 3,4-dimethoxybenzyl (DMPM) perfluoroimidates

  摘要：

  We have succeeded in one-pot preparation of perfluoroimidates at -78 degrees C by employing the dehydration of perfluoroamide under the "activated" dimethyl sulfoxide (DMSO) species followed by in situ nitrile trapping with alcohols. MPM and DMPM perfluoroimidates can be used to protect alcohols in place of the trichloroacetimidate with excellent chemical properties and in comparable yields. (C) 1998 Elsevier Science Ltd.

  Various types of primary amides were treated under an activated dimethyl sulfoxide (DMSO) species, (COCl)(2)-DMSO and Et3N, as a dehydrating agent to obtain nitriles in excellent yield. This dehydration system was extended to a one-pot preparation of perfluoroimidates via volatile perfluoronitriles from perfluoroamides. Fifteen benzyl-type perfluoroimidates can be prepared in 70-90% yield as more stable imidates than the trichloro analogue. MPM- and DMPM-perfluoroimidates can be used to protect alcohols in place of the trichloroacetimidate with excellent chemical properties and in comparable yields. (C) 2002 Elsevier Science Ltd.
