Zur Synthese von Isosantalol und δ-Santalol

The syntheses of the title compounds are described. A short convergent synthesis leads from camphenilone to isosantalol (4). -Santalol (18) can be prepared step by step starting from isocamphenilanol9. Coupling reactions did not succeed. Some byproducts have been found. One of them possesses a cedarwood-like scent and the way of its formation is discussed. The odour properties of4 and18 are discussed briefly.
