Abstract
1530118 Acyl cyclohexenes BUSH BOAKE ALLEN Ltd 13 Oct 1975 [12 July 1974] 31039/74 Heading C2C [Also in Division A5] The invention comprises derivatives of 2,6,6- trimethyl cyclohex-(1 or 2) ene containing in the 1 position a group of the formula -COR -where R is alkyl of 2, 4 or 5 carbon atoms. The compounds may be prepared by reacting α- or #-cyclocitral with a compound of the formula RMgBr and oxidizing the product. The compound wherein R has 3 carbon atoms may be prepared similarly. The compounds may be used in perfume compositions.
