STRUCTURE - ODOR CORRELATION - IX: FROM 1,8-CINEOL TO SESQUICINEOL - CHANGE OF ODOR WITH STRUCTURE

Cu(I) catalyzed 1,4-Grignard reaction of the key compound 6 led to the bicyclic keto ethers 7-15 together with small amounts of the alcohols 16-25.Wolff-Kishner reduction of 8-15 gave the 1,8-cineol homologues 26-32 and sesquicineol (2). - The fresh and camphoraceous odor of 1 changes stepwise with increasing side chain to herbaceous and spicy notes, compounds with branched side chains show lavender undertones. 2 has a pleasant fruity, floral and sweet fragrance.
