NEW MATERIAL:Compounds represented by formula I (R1 and R2 are H or alkyl where the total number of C is 3-7 or R1 and R2 form six-membered ring together with two C on cyclohexane ring). EXAMPLE:2-(2- or 4-t-Butylcyclohexyl)-1-propanal. USE:A component of a perfume composition. Having excellent fragrances such as green-like, wood-like, flower-like, grass-like, orris-like, spice-like, grapefruit- like, amber-like or mint-like one, used as a material for preparation of a perfume and capable of blending in perfumes, soaps, shampoos, house perfumes, detergents, etc. PREPARATION:The objective compound of formula I is readily obtained by heating a 2-(alkylcyclohexyl)-1-propanol of formula II in the presence of a dehydrogenation catalyst such as Cu-Cr catalyst in a solvent such as liquid paraffin or by reacting the 2-(alkylcyclohexyl)-1-propanol with an oxidizing agent such as pyridinium chlorochromate in an organic solvent such as methylene chloride. |
