Statin drugs are some of the most effective drugs in the battle against high cholesterol. They are the most efficacious in lowering LDL cholesterol. Furthermore‚ recent studies have shown that statins are capable of preventing heart attacks and reducing the risk of strokes. However‚ statins are only recently gaining public attention though they have been available for many years. Various cholesterol-lowering agents had been discovered during the 1950s and 1960s. However‚ the majority had unwanted

The SN2 reaction requires three qualities: a strong nucleophile‚ a good‚ unhindered leaving group‚ and a polar‚ aprotic solvent. For our reaction‚ we have all three bases covered. The nucleophile is an alkoxide‚ a deprotonated alcohol. Technically‚ because our alcohol is a phenol‚ the conjugate base is called a phenoxide. Phenol itself has a pKa of about 10‚ but our alcohol has more resonance opportunities‚ so the pKa is down around 8. This is sufficiently acidic for use of weak base like K2CO3 for
