Optically active [m.n.l]propellanones have been prepared by diastereoselective cyclopropanation of homochiral ene ketals derived from 1,4-di-O-benzyl-L-threltol and readily available bicyclic enones. Propellanones are a synthetically useful subset of the structurally and theoretically interesting pr

## Abstract A new synthesis of (−)‐(__R__)‐muscone ((__R__)‐**1**) by means of enantioselective protonation of a bicyclic ketone enolate as the key step (see **6**→(__S__)‐**4** in __Scheme 2__) is presented. The C~15~ macrocyclic system is obtained by ozonolysis (__Scheme 7__).
