methods for their preparation mainly rely on thermal [3 + 2] cycloaddition of potentially dangerous acetylene and azides. Here we report a base-mediated [4 + 1] annulation of azoalkenes generated in situ from readily available difluoroacetaldehyde N-tosylhydrazones (DFHZ-Ts) with amines under relatively mild conditions. This azide- and acetylene-free strategy provides facile access to diverse 1-substituted

This paper details a simple and efficient 3-component synthesis of 1-substituted 1,2,3-triazoles using a primary amine, 2,2-dimethoxyacetaldehyde and tosylhydrazide. The reaction proceeds in good to excellent yields using either aliphatic or aromatic amine substrates and is tolerant of a wide range of functional groups including electron-rich and deficient aryl groups, terminal alkynes, ketones and
