Process for producing cyclohexenes

A process for producing 3-(5-hydroxy-3-methyl-1,3-pentadienyl)-2,4,4-trimethyl-2-cyclohexen-1-one, an intermediate for canthaxanthin, by hydrogenation of 5-(2,6,6-trimethyl-3-oxo-cyclohexen-1-yl)-3-methyl-2-penten-4-yn-1-ol with zinc and a carboxylic acid.

Hydroxy-acetylene-substituted cyclohexenone

A total synthesis of canthaxanthin or dinor-canthaxanthin, known food coloring agents, from pentols.
