Abstract
New substituted 1-alkenynyl-cyclohexanols and 1-alkenynyl-cyclohexenes. The 1-alkenynyl-cyclohexanols are obtained by reacting the corresponding cyclohexanone witn an enyne in the presence of a strongly basic condensing agent in an inert solvent, or with an alkali metal salt of an enyne in an inert solvent. The 1-alkenynyl-cyclohexenes are obtained by dehydrating the 1-alkenynyl-cyclohexanols or 1-cycloalkanolyl-alkynols. The new compounds are themselves interesting scents, but can also be used as starting materials for further interesting scents.
