Identification of the Regioselectivity of the Thermal Huisgen 1,3-Dipolar Cycloaddition Reaction between an Azide Derivative and a Synthetic Heterocyclic Alkyne, through a Comparative Study of NMR Spectral Data | Chapter 12 | Theory and Applications of Chemistry Vol. 4

The 1,3-dipolar cycloaddition reaction between 4-(azidomethyl)-4-methyl-2-phenyl-4,5-dihydrooxazole and 9-(prop-2-ynyl)-9H-carbazole, in toluene at reflux, leads to obtain two regioisomers with different proportions where the 1,4-regioisomer is generally more prominent than 1,5-regioisomer. The assignment of structures to 1,2,3-triazolic regioisomers was established in base of a comparative study of NMR spectral data (1H, 13C, 15N and 2D 1H-15N HMBC spectra) in addition to the elemental analysis and MS data.
