Phosphoric Acid → HCID 20287635, compound

Participants

Reaction Steps

The procedure of Example I was applied to a sample of 5-methyl-6-(4-methyl-3-pentenyl)-6-hepten-1-ol. This was stirred with 85 percent phosphoric acid for one hour at room temperature, and the ether-soluble, water-insoluble reaction product was chromatographed on alumina. A relatively non-polar material was eluted from the column immediately (polar materials such as alcohols remained on the column). The eluted product was identified by means of NMR and IR as 2-methyl-2-(3',3'-dimethylcyclohexyl)-tetrahydropyran.
