Chemospecific Preparation of Both Enantiomers of α-Terpinyl Trifluoroacetate

(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 1 H and 13 C NMR, IR and MS and theirs Chiral-HRGC analysis showed there is no loss...

Description
Summary:(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 1 H and 13 C NMR, IR and MS and theirs Chiral-HRGC analysis showed there is no loss of optical activity during the reaction.
