Abstract
Improved processes for preparation of high enantiomeric purity compounds center on resolution using simulated moving bed chromatography of a racemic precursor early in the synthesis. Resolution is effected with high enantiomeric purity, and subsequent reactions of the desired enantiomer performed with high optical specificity to maintain enantiomeric purity. The undesired enantiomer is racemized and recycled to the resolution phase to avoid loss.
