Synthesis of Some Substituted 1,2,3-Triazole Derivatives via 1,3-Cycloaddition Reaction of Phenacylazides and Some Substituted Propargyl Compounds

Abstract

Some propargyl esters (5a-g) were prepared from the reaction of propargyl alcohol (2) with the corresponding acid chlorides (1a-g). Also some propargyl imides (6a-c) were prepared from the reaction of the corresponding imide sodium salts (4a-c) with propargyl bromide (3). The two series of compounds (5a-g,6a-c) were allowed to undergo 1,3-cycloaddition reaction with phenacyl azide (9) which intern prepared from the reaction of phenacyl bromide (7) and sodium azide (8) to form the final substituted 1,2,3-triazoles (10a-j). The above synthesized compounds were characterized by IR spectroscopy and are discussed.
