Synthesis and Characterization of N-((tetrazol-5 yl)methyl)cyclohexanamine through 2D NMR Experiments: An Overview| Chapter 10 | Theory and Applications of Chemistry Vol. 4

Tetrazoles are an important class of nitrogen containing heterocycles with a wide range of medicinal and commercial applications. Tetrazolyl analogs of amino acids exhibit versatile biologic activity, and some of them are known pharmaceuticals. In addition, compounds of this type may be using in development of radiopharmaceuticals for positron emission tomography.

In continuation of our investigations in the tetrazolic amino acids, we described in this presentation the synthesis and characterization of some aminoalkyl and tetrazolic amino acid derivatives basing on different spectroscopic methods as NMR 2D.

A simple synthetic approach to N-((tetrazol-5-yl)methyl)cyclohexanamine in two steps starting from chloroacetonitrile and cyclohexylamine is reported. The synthesized compound was characterized by 2D NMR spectroscopy (1H, 13C) and elemental analysis data.

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 was also tested in vitro for its antibacterial activity against Gram-positive bacteria (Staphylococcus aureus) and Gram-negative bacteria (Escherichia coli). The calculation of MBC/MIC ratio showed that this triazole derivative 2 had a bactericidal effect on the two strains tested.
