The Lossen rearrangement, that allows the conversion of hydroxamic acids into isocyanates,
was discovered almost 150 years ago. For more than a century, this transformation was …

The review is devoted to the methods of synthesis of pyridine-substituted ureas and
carbamates. The classical synthetic approaches to such compounds together with the …

A mild and metal-free synthesis of aryl isocyanates from arylamines under an atmosphere of
CO2 was developed. The carbamic acid intermediate, derived from the arylamine starting …

A variety of aromatic and aliphatic hydroxamic acids were converted to the corresponding
primary amines via base-mediated rearrangement. This rearrangement could proceed with …

Amides are prevalent in pharmaceuticals, agrochemicals, and materials.
Hydroaminocarbonylation of alkenes has emerged as one of the most direct and rapid …

Two biological activities of butyrate in the colon (suppression of proliferation of colonic
epithelial stem cells and inflammation) correlate with inhibition of the activity of histone …

The Lossen rearrangement is a classic process for transforming activated hydroxamic acids
into isocyanate under basic or thermal conditions. In the current report we disclosed a …

Electrophilic amination (EA) involving transition metal-catalysed CH activation of the arene
has recently emerged as a promising method to directly construct aryl C (sp 2)-N bonds. In …

Oxy-carbamate O-isocyanate precursors facilitate access to synthetically valuable N-
oxyureas via substitution with amines. This work exploits the reactivity of suitable O …

An cascade intramolecular 5‐exo‐dig cyclization of N‐(2‐iodophenyl) propiolamides and
sequential amination/etherification (with N‐hydroxybenzamides, phenyl hydroxycarbamate) …
