Curtius Rearrangement




The isocyanate can be trapped by a variety of Nucleophile s. Often water is added to Hydrolyze the isocyanate to an Amine . When done in the presence of Tert-butanol , the reaction generates BOC - Protected amines, useful intermediates in Organic Synthesis .

Carboxylic Acid s 1 can be easily converted to acyl azides '''3''' using Diphenylphosphoryl Azide '''2'''.

Likewise, when the Curtius reaction is performed in the presence of Benzyl Alcohol , Cbz-protected amines are formed.
