Abstract
1,203,871. Polyenic alcohols and ketones. BADISCHE ANILIN- & SODA-FABRIK A.G. 31 Jan., 1968 [1 Feb., 1967], No. 4926/68. Heading C2C. [Also in Divisions A5-A6] The new compounds 6, 10,14-trimethylpentadecatrien - (5,9,14) - one - (2) and 6,10 - di - methylundecadien - (5,10) - one - (2) are prepared by treating a compound of general formula wherein m is zero or 1, with an agent for introducing the acetone group. Such agents are an acetoacetic ester, diketene, an isopropanyl ether, a ketal of acetone, an enol ether, or an acetal of 3-oxobutanol. 3,7,11 - Trimethyldodecadien - (6,11) - in - (1) - ol-3 is prepared by ethynylating 6,10-dimethylundecadien - (5,10) - one - (2). This latter compound is reacted with a vinyl Grignard compound and the product hydrolysed, or else the former compound is partially hydrogenated, in both cases to give 3,7,11-trimethyldodecatrien- (l,6,11)-ol-(3).
