Enamines; Part 46. Synthesis of 5-Dialkylamino-1-aryl-1,2,3-triazoles Functionalized at C-4

Article abstract of DOI:10.1055/s-1986-31851

Aryl azides undergo a <3+2>-cycloaddition with 1,1-diaminoethenes having an electron-withdrawing group at C-2 to give unstable 5,5-diamino-4,5-dihydro-1,2,3-triazoles from which one amino group is eliminated to afford 5-amino-1-aryl-1,2,3-triazoles functionalized at C-4.
