Novel triazolyl derivatives for acidic release of amines

Add time:08/02/2019    Source:sciencedirect.com

Triazolyl derivatives of amines were prepared using click chemistry and evaluated as releasing systems in mildly acidic environments. Triazolylcarbamates and alkylamines were obtained, depending on the reactivity of the propargylic intermediates used for the Huisgen cycloaddition. A fast hydrolysis of some derivatives in mildly acidic conditions was achieved. The relative rates were correlated to a proposed mechanism highlighting the complementary role of the triazole ring and carbocation reactivity/stability.
