Organocatalytic Vinyl Azide-Carbonyl [3+2] Cycloaddition: High-Yielding Synthesis of Fully Decorated N-Vinyl-1,2,3-Triazoles

For the first time, an enolate-mediated organocatalytic vinyl azide-carbonyl [3+2] cycloaddition (OrgVACC) of various ketones/aldehydes with vinyl azides is reported. It is an efficient intermolecular reaction with excellent outcomes with reference to rate, yield, selectivity, operational simplicity, substrate scope, catalyst simplicity, and vast applications.
