Method for preparation of cyclic myrac aldehydes from myrac aldehyde catalyzed by zinc-containing ionic liquid

The invention provides a novel method for catalyzing cyclization reaction of myrac aldehyde for conversion to cyclic myrac aldehydes by using a Lewis acidic ionic liquid as a catalyst. According to the method, by using a zinc-containing ionic liquid as a catalyst and under the mild condition, 4-(4-methyl-3-pentenyl)-3-cyclohexenal(p-myrac aldehyde) and 3-(4-methyl-3-pentenyl)-3-cyclohexenal (m-myrac aldehyde) undergo selective cyclization to prepare cyclic myrac aldehydes (1,2,3,4,5,6,7,8-octahydro-,8,8-dimethyl-2-naphthaldehyde and 1,2,3,4,5,6,7,8-octahydro-5,5-dimethyl-2-naphthaldehyde). Incomparison with a traditional cyclic myrac aldehydes production method, the invention has the following distinctive characteristics: the use of a volatile organic solvent is avoided in the reaction; the reaction condition is mild; the target product has high selectivity, and the reaction is rapid; after the reaction, the ionic liquid catalyst and the product are automatically layered and are convenient to separate; the ionic liquid catalyst is recyclable; generation of a waste acid solution by traditional catalysis is avoided; and the method is environmentally friendly.
