Synthesis of Novel Sugar Amino Acids by Curtius Rearrangement

European Journal of Organic Chemistry, 2003
AbstractSugar amino acids (SAAs) bearing an amine group on the anomeric position are a challenging class of SAAs to synthesize due to the inherent instability of glycosylamines. We developed a novel synthetic strategy towards both furanoid and pyranoid δ‐SAAs of this type, based on a Curtius rearrangement. The latter reaction, which is known to proceed

Synthesis of 2-Arylethylamines by the Curtius Rearrangement

Synthetic Communications, 2010
2-Arylethylamine derivatives were synthesized using the Curtius reaction and with three different methods of preparing the acyl azide functional group. Carbamates derived from isocyanate were convenient protecting groups for alkylation of amines.
