A convenient method toward the synthesis of α-amino acid-derived unsymmetrical ureas 2 is described herein. This route involves an interesting rearrangement of amides of N-Cbz-α-amino acids 1, which presumably entails the intermediacy of hydantoins that is followed by hydrolysis to afford unsymmetrical ureas 2 in quantitative yields and high purity.
Described herein are Janus kinase (JAK) inhibitors and methods of utilizing JAK inhibitors in the treatment of diseases, disorders or conditions. Also described herein are pharmaceutical compositions containing such compounds.
