Abstract
NEW MATERIAL:A tricyclic spiro-alcohol of formula I (the dotted line may or may not be present).
EXAMPLE: Exo-5-norbornene-2-spiro-1'-cyclopentan-2'-ol.
USE: Perfumes having a lasting fragrance like camphor.
PROCESS: Exo-5-norbornene-2-spiro-1'-cyclopentan-2'-one of formula II or exo- norbornene-2-spiro-1'-cyclopentan-2'-one of formula III (the formulas II and III are generically called tricyclic spiro-ketones) is reduced with a metal hydride, e.g. NaBH4, to form the compound of formula I, e.g. exo-5-norbornene-2-spiro-1'- cyclopentan-2'-ol or exo-norbornane-2-spiro-1'-cyclopentan-2'-ol.
