An enzymatic approach to the synthesis of all the possible stereoisomers of (E) and (Z), cis and trans-γ-irones in enantiomerically pure form from commercial Irone Alpha is described. A very efficient resolution of racemic trans-γ-irone, affording both the enantiomers in high ee and chemical purity, is also presented. Olfactory evaluation of (+)- and (-)-3b and full configuration assignment of the irone isomers contained in samples of Italian iris oil are reported.
Synthesis of (+)-(2S,6S)-trans-α-Irone and of (-)-(2S,6S)-trans-γ-Irone

A 3:1 mixture of (+)-(2S,6S)-trans-α-irone ((+)-1) and (-)-(2S,6S)-trans-γ-irone ((-)-2) has been synthesized with ca. 70 percent e. e. by the ene reaction of (-)-(S)-3 and but-3-yn-2-one.

(+/-)-cis-γ-Irone (1a), (+/-)-cis-dihydro-γ-irone (2a) and their trans-isomers (1b, 2b) were synthesized via 3,3-(Claisen) or 2,3-sigmatropic rearrangement of 1-hydroxymethyl-3,3,4-trimethyl-1-cyclohexene (8) derivatives as each key step.
