A simple one-pot conversion of carboxylic acids to carbamates is achieved by propylphosphonic anhydride (T3P) in combination with azidotrimethylsilane and an alcohol via the Curtius rearrangement. Besides diverse primary to tertiary alcohols, t

(Chemical Equation Presented) An efficient and stereospecific approach to the synthesis of structurally constrained aza-, oxa-, and thiabicyclo[3.1.0] hexane heterocycles has been achieved through application of the intramolecular cyclopropanation reactio
Palladium-catalyzed intermolecular coupling of aryl halides and amides

The first general intermolecular C-N bond-forming reactions between aryl halides and amides were realized using a palladium catalyst with Xantphos as the ligand. Aryl triflates, carbamates, and sulfonamides are also viable substrates for the amidations, which proceed at 45-110 °C with 1-4 mol% of Pd catalyst in 66-99% yields and exhibit good functional group compatibility.
