The catalytic asymmetric Friedel-Crafts reaction of silyl enol ethers with
fluoral proceeds under Mukaiyama-aldol conditions to give silyl enol ether
products. The sequential diastereoselective reactions of the resultant sily
l enol ethers with electrophiles provide highly enantiopure functionalized
organofluorine compounds of material and pharmaceutical interest.
