Synthesis, 1H and 13C NMR study of pyrazoles derived from chiral cyclohexanones (3-methylcyclohexanone, menthone, pulegone, dihydrocarvone and carvone)

The 1H and 13C chemical shifts of four tetrahydroindazoles (two of them existing as diastereomeric mixtures) and one aldazine were measured and assigned. These compounds were obtained from monoterpenic ketones (R)-(+)-3-methylcyclohexanone, (2S, 5R)-(-)-menthone, (R)-(+)-pulegone, (5R)-(+)-dihydrocarvone, and (R)-(-)-carvone in a two-step procedure. The annular tautomerism in CDCl3 solution was calculated and compared with ab initio calculations (B3LYP/6-31G*).

Quantitative analyses of the seven isomeric 3,4- and 3,6-dimethylcyclohexenes by gas chromatography

Quantitative analyses of mixtures of the seven isomeric 3,4- and 3,6-dimethylcyclohexenes have been achieved by gas chromatography. Correlations of structure and absolute stereochemistry with elution order have been made rigorously with the aid of authentic optically active samples all derived from (3R)-methylcyclohexanone.
