Syntheses are described from a common labeled intermediate of P-cyanoalanine, asparagine, and aspartic acid, each of the L conjiguration and labeled with carbon-14 in carbon-four. Radiochemical purities were 96, 99.7, and 99 %. The common source of carbon-14 was ethyl aCetyl-DL-P-~yanoalaninate-4-~~
## Abstract Stereoselective syntheses of (±)‐epi‐β‐santalene **(1)** and (±)‐epi‐β‐santalol **(2)**, minor constituents of East Indian sandalwood oil, are described. The starting material for both syntheses is the tricyclic hemiacetal **4**, readily accessible in two steps from norbornene.
