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,...

Synthesis, Characterization and Antibacterial Activity of Diethyl 1-((4-Methyl-2-phenyl- 4,5-dihydrooxazol-4-yl)methyl)-1H-1,2,3-triazole-4,5-dicarboxylate: Advanced Study| Chapter 8|Theory and Applications of Chemistry Vol. 4

The compound, diethyl 1-((4-methyl-2-phenyl-4,5-dihydrooxazol-4-yl)methyl)-1H-1,2,3-triazole-4,5-dicarboxylate 2, was synthesized in high yield, through 1,3-dipolar cycloaddition reaction of 4-(azidomethyl)-4-methyl-2-phenyl-4,5-dihydrooxazole and diethyl but-2-ynedioate in the absence of a solvent. The structure of the synthesized compound was established on the basis of NMR spectroscopy (1H, 13C), X-ray crystallography and MS data. The prepared compound...

Structure Assignment of the Two Isomers of 2-(1H-1,2,3-Triazol-1-yl)-Glycine N-Protected by Spectroscopic Methods and by Chemical Pathway| Chapter 4 | Theory and Applications of Chemistry Vol. 4

We describes in this chapter, the assignment of the 1,4- and 1,5-regioisomer structures of N-protected 2-(1H-1,2,3-triazol-1-yl)-glycine derivatives on the basis of 1H NMR, IR and chemical pathway. A subsequent assignment of 1,4- and 1,5-regioisomer structures of biheterocyclic glycine derivatives and their phosphonic analogues were based on spectroscopic study in...
