Significance

Fluvastatin is an HMG-CoA reductase inhibitor marketed as a racemate. The key step in the synthesis depicted was the enantio­selective addition of diketene E to the aldehyde C mediated by the enantiopure Schiff base D and ­titanium isopropoxide. The stoichiometric version of the reaction shown gave the α-hydroxy ketone H in 78% yield (er = 96:4), whereas 10 mol% of (S)-D delivered H in 70% yield (er = 87:13).
