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

Some Applications of the Curtius Rearrangement

Journal of the Chemical Society, Perkin Transactions 1, 1983
Pairs of optically pure enantiomers of substituted 1,1 -diamines have been prepared from the azides of L-amino-acids via the Curtius rearrangement.This synthesis is based on the interchange of two groups attached to the asymmetrically substituted tetrahedral α-carbon atom of the parent amino acid.

Improved Preparation of Tyramine by Curtius Rearrangement

Chinese Journal of Chemistry, 2009
AbstractAn improved and facile preparation of tyramine [2‐(p‐hydroxyphenyl)ethylamine] was described, which starts from phenol and acrylonitrile to form β‐(p‐hydroxyphenyl) propionic acid via Friedel‐Craft's alkylation and nitrile hydrolysis. After hydrazinolysis and a subsequent Curtius rearrangement, tyramine was obtained in 30.2% total yield.

Curtius-type rearrangement of a sulphonyl azide

Journal of the Chemical Society D: Chemical Communications, 1969
Six products have been identified from the thermolysis of mesitylene-2-sulphonyl azide in dodecane: two are derived from a Curtius-type rearrangement of the corresponding sulphonyl nitrene.
