Four-component one-pot synthesis of novel dicyanoaniline-anchored triazoles

A four-component reaction was developed by taking advantage of the reactivity of propargyl functional groups residing on primarily formed dicyanoaniline products. Various enolizable cyclic ketones were reacted with malononitrile and 4-(prop-2yn-1-yloxy)benzaldehyde derivatives in an aqueous t-BuOH/NaOH medium, and the resulting dicyanoanilines were subjected to a subsequent in situ click reaction to obtain the final dicyanoaniline-anchored triazole products. The enhanced photophysical properties of the novel products are currently under study.
