The advantages of the "naked carbon skeleton" strategy in the totalsynthesis of polyoxygenated natural products are demonstrated in the totalsynthesis of the 18-membered macrolide (+)-aspicilin, 1. This approach employs the easily prepared, nonfunctionalized carbon skeleton of the target molecule, hexadeca-1,3,15-triene, 2. All the required stereogenic carbinol centers are then introduced onto this
