NEW MATERIAL:Norbornene derivatives of formula I: (R is 3-8C alkyl group at any one of the 1,- 4,- 5-, and 6-positions; X and Y form a corbonyl group together with the corbon atom at the 2-position, one of them is OH and the other is H).
EXAMPLE: 1-Pentyl-5-norbornene-2-one.
USE: Flower like fragrance components in compounded perfumes of general cosmetics, and mixed perfumes, e.g. perfumed water, etc. Physically and chemically stable and free from irritation and toxicity.
PROCESS: Compounds of formula II are subjected to alkylation by alkyl halides cyclization, and addition by dienophiles to form compounds of formula III: (A and B are substituents equivalent to ketones). The substituents equivalent to ketones are changed to ketones to form alkyl-5-norbornene-2-ones, which are reduced to give alkyl-5-norbornene-2-ols of formula I, if necessary.
