Abstract

Enantioselective approaches to the formation of α,β-disubstituted ketones through aldol reactions are compared. A one-pot ACA/aldol domino process is lower yielding than alternative procedures involving enantiomerically pure β-substituted silyl enol ethers. The use of chiral acetals derived from hydrobenzoin provides access to syn and anti diols in moderate to good yields and high diastereoselectivities. A novel synthesis of functionalized β,γ-unsaturated acetals is also described.
