Progress of synthesis of (R)-2-chloromandelic acid

(R)-2-chloromandelic acid is one of the most important intermediates and fine chemicals with broad use. It can be used for the synthesis of clopidogrel，an anti-platelet drug that inhibits the ability of platelets to clump together as part of a blood clot. Presently，(R)-2-chloromandelic acid can be prepared by asymmetric synthesis and resolution of racemate. This review introduces various preparation methods of (R)-2-chloromandelic acid，and compares the advantages and disadvantages of these methods. The prospect of (R)-2-chloromandelic acid synthesis methods is also discussed.
