Resumo:

Cyclohexanone and 2-, 3- and 4-methylcyclohexanones have been condensed with acetylene to give the respective 1-ethinylcyclohexanola. The 1-ethinylcyclohexanols were hydrogenated to the respective 1-vinyl- and 1-ethylcyclohexanols. The 1-vinylcyclohexanols have been treated with phosphorus tribromide to give the corresponding rearranged β-cyclohexylidenethyl bromides which have been converted to the pyridinium salts. The latter were treated with p-nitrosodimethylaniline and alkali (Krohnke's method) to give the corresponding nitrones which were hydrolyzed to the corresponding aldehydes. The 1-ethinyl-, 1-vinyl- and 1-ethylcyclohexanols prepared were subjected to pharmacological tests.
