Two stable hemiaminals, N acylated by the p-nitrobenzoyl or Boc group and each substituted by the difluorocarboxylethylester moiety, were obtained in a single step from the corresponding ethylhemiacetal. The Boc compound, after acylation by trifluoroacetic anhydride followed by in situ reaction either with trimethylsilylated derivatives of cyanide or diethylphosphite, or with sodium sulfite, led to the protected carboxylic, phosphonic, and ...
