Page/Page column 7, (2008/06/13)
The present invention relates generally to perfluoroalkyl chiral auxiliary compounds and methods of manufacture. These compounds have the functionality to effectively support the synthesis of chiral compounds in single reactions, high-throughput parallel recations, or combinatorial reactions The invention relates to two oxazolidmone chiral auxiliaries (1) and (2): wherein Rf is a perfluoroalkyl group having the general formula (CH2)x-CyF2y+1 where x = 1-5 and y = 4-10 and wherein B is an unfunctionalized aryl, alkyl or arylalkyl group Pn a preferred embodiment, x = 2 and y = 6 and B is derived from unfunctionalized ammo acids The ammo acids may be from either the D- or L- series, and are preferably enantiomeπcally pure or in very high enantiomeric excess in either configuration.

The title synthesis could be accomplished by employing highly stereoselective aldol reaction of O-methyl-O-trimethylsilyl ketene acetal with the (S)-α-amido aldehyde (2) in the presence of titanium (IV) chloride as a key step.
