The one-pot synthesis of multisubstituted pyrazole derivatives was achieved viacatalyst-free 1,3-dipolar cycloaddition of ethyl diazoacetate and nitroalkenes as the key step and elimination of the leaving group (NO2 or Br) followed by intramolecular proton transfer with satisfactory yields.
A simple and efficient protocol has been developed for the synthesis of 1,2,3-triazole derivatives by catalyst-free1,3-dipolarcycloaddition of nitroalkenes with sodium azide undermildconditions.
