Chemospecific Preparation of Both Enantiomers of α‐Terpinyl Trifluoroacetate

Abstract

(R)‐ and (S)‐α‐Terpinyl trifluoroacetate can easily be prepared in 56–64% yield and high ee by the reaction of (R)‐ and (S)‐limonene with trifluoroacetic acid in cyclohexane. The products were fully characterized by 1H and 13C NMR, IR and MS and theirs Chiral‐HRGC analysis showed there is no loss of optical activity during the reaction.
