Abstract

-2-Bromoesters enriched in the (S,R)-diastereoisomer can be easily pre pared by coupling of racemic 2-bromoacids with (R)-pantolactone. Displacement of the bromine atom with nucleophiles, under suitable reaction conditions, occurs without epimerization of starting compounds, giving (R,R)-2-substituted carboxylic acid derivatives.
