A stereoselective synthesis of a C1–C11 building block for the polyol-polyene antibiotic rimocidin has been developed. Its functional groups originate from a disubstituted indane, which underwent Birchreduction, and oxidative cleavage. This provided a dihydropyranone with a β-keto ester side-chain. The latter was subjected to a Noyori hydrogenation (ds > 97:3). An oxy-Michael addition gave a mixture
