DMAP Catalyzed One-Pot Curtius Rearrangement Using 1,1-Dimethyl-2,2,2-trichloroethoxycarbonyl Azide.
Organic Letters, 2023We report our development of a controllable, base-free, one-pot Curtius rearrangement using 1,1-dimethyl-2,2,2-trichloroethoxycarbonyl azide (DMTN3) with 4-(dimethylamino)pyridine (DMAP) as a catalyst.

The hydroxytetrahydropyrrolo-imidazolidinone (HTHP-I) core present in colensolide A is a synthetically intriguing scaffold as a result of its high heteroatom/carbon ratio and perceived instability.

Synthesis of New Dialkyl 2,2′-[Carbonylbis(azanediyl)]dibenzoates via Curtius Rearrangement
Synthesis, 2021The 2-(alkylcarbonyl)benzoic acids obtained by esterification of phthalic anhydride are converted into azide derivatives: alkyl 2-[(azidocarbonyl)amino]benzoates and to ureas: dialkyl 2,2′-[carbonylbis(azanediyl)]dibenzoates.

Some Applications of the Curtius Rearrangement
Journal of the Chemical Society, Perkin Transactions 1, 1983Pairs 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.
