Statins are inhibitors of 3‐hydroxy‐3‐methyl‐glutaryl coenzyme A reductase (HMG‐CoA reductase) and became the standard of care for treatment of hypercholesterolemia because of their efficacy, safety, and long‐term benefits. They are administered as diastereo‐ and enantiomerically pure compounds. We summarize here two new approaches for the totalsynthesis of the most important representatives, atorvastatin

The highly enantioselective hydrogenation of ethyl 5,5-dimethoxy-3-oxopentanoate (3) to ethyl 3-hydroxy-5,5-dimethoxypentanoate (4) – a keyintermediate in the synthesis of pharmacologically important statin drugs – has been investigated. The stereochemistry of the catalytic hydrogenation of the β-keto ester in the presence of a number of homogeneous chiral RhI and RuII complexes with phosphane ligands
