ABSTRACT:
The cyclic Isolongifolanone ketals of the general formula A wherein the wavy lines mean .alpha.- and .beta.-configuration and R,R' mean radicals of hydrogen, methyl or ethyl, are new. With preference they are used either as odorants or as components of perfume compositions. They are manufactured from Isolongifolene which is itself produced from Longifolene as is well known. Isolongifolene is oxydized to Isolongifolene-3-on and this is reacted with aliphatic 1,2-diols in apolar solvents with the separation of water.
