    Abstract

    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 excel- lent 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 highly sterically encumbered amines
