Application
Evan′s chiral auxiliary (4R,5S)-(+)-4-Methyl-5-phenyl-2-oxazolidinone reacts with carboxylic acids to produce corresponding acyl derivatives in the presence of a diisopropylcarbodiimide reagent. It can also employed in the preparation of N-sulfinyloxazolidinone reagent (chiral sulfinyl transfer reagent), which reacts with nucleophiles such as Grignard reagents, enolates, and metalated amides to produce the chiral sulfoxides, sulfinate esters, and sulfonamides.
