Stereospecificity of the Curtius rearrangement [PDF]

open access: bronzeCanadian Journal of Chemistry, 1968
Jones and Mason claimed a number of years ago (1) that rearrangement of cis-olefinic acyl azides gave trans-olefinic isocyanates. However, several other workers have found that rearrangement of an acyl azide group attached to an optically active carbon gives configurationally identical products, a discovery which apparently conflicts with Jones and ...

N,N′-Dibenzylethylenediammonium dichloride [PDF]

open access: yesActa Crystallographica Section E: Crystallographic Communications
The isolation and crystalline structure of N,N′-dibenzylethylenediammonium dichloride, C16H22N22+·2Cl−, is reported. This was obtained as an unintended product of an attempted Curtius rearrangement that involved benzylamine as one of the reagents and 1,2-

Coupling biocatalysis with high-energy flow reactions for the synthesis of carbamates and β-amino acid derivatives [PDF]

open access: yesBeilstein Journal of Organic Chemistry, 2021
A continuous flow process is presented that couples a Curtius rearrangement step with a biocatalytic impurity tagging strategy to produce a series of valuable Cbz-carbamate products.

ONE-POT SYNTHESIS OF FUSED 2-PYRIDONES FROM HETEROARYLACRYLIC ACID VIA CURTIUS REARRANGEMENT AND MICROWAVE-ASSISTED THERMAL ELECTROCYCLIZATION

open access: gold, 2017
– We investigated the one-pot synthesis of several fused 2-pyridone ring systems based on a Curtius rearrangement, followed by a microwave-assisted thermal electrocyclization of a 2-aza-6  -electron system including isocyanate.
