Title: Novel unsaturated ethers and a process for their manufacture
IPC: C07C43/14
Filed: 1963-03-15
Abstract: The invention comprises compounds of formula <FORM:0969305/C1/1> where X is -C­CH or -CH=CH2, R1 and R2 may be H or lower alkyl and R3 is a lower alkyl group. The alkyl groups have 1-6 C. atoms The compounds are prepared by hydrating a compound of formula <FORM:0969305/C1/2> using preferably, a mixture of 1-3 parts by weight sulphuric acid, 2-6 parts by weight of acetic acid, and 2-6 parts by weight of water to each part by weight of starting material. The reaction is carried out at 20-100 DEG C., preferably 40-50 DEG C. When temperatures of 40-50 DEG C. are used, the reaction is complete in 3-8 hours. The hydration products are obtained by diluting the mixture formed, and extracting it with ether. The acetylenic ethers so obtained may be reduced to ethylenic ethers by selective hydrogenation, e.g. by catalytic hydrogenation. The hydration product is dissolved in an inert, water-immiscible solvent e.g. hexane, any hydrogenation catalyst may be used but the preferred catalyst is a lead-inhibited palladium/calcium carbonate catalyst. Examples indicate the preparation of 3,7-dimethyl -3- methoxy-octyne -1- ol-7, and the octen -1- ol-7, 3-methoxy-3, 6, 7-trimethyl-octyn -1-ol-7, 3, 7-dimethyl-3-methoxy-nonyn -1- ol-7, and nonen -1- ol-7, and 3, 7-dimethyl -3- ethoxy-nonyn -1- ol-7 and the corresponding-nonen -1- ol-7. The preferred compound is 3, 7-dimethyl -3-ethoxy-nonyn -1- ol-7. The compounds have a fine fragrance and may be used as odorants in the preparation of perfumes and other scented compositions.
