G. Ulibarri et al., ACTIVATION OF IMIDAZOLIDES USING METHYL TRIFLUOROMETHANESULFONATE - ACONVENIENT METHOD FOR THE PREPARATION OF HINDERED ESTERS AND AMIDES, Synthesis, (11), 1996, pp. 1286
Treatment of imidazolides with methyl trifluoromethanesulfonate follow
ed by reaction with alcohols or amines provides a convenient one-pot p
rocedure for thr preparation of esters and amides. The method is appli
cable to imidazolides of low reactivity as well as to hindered nucleop
hiles.
