Notes:
The structure of carquejol is amended to that of cis-3-hydroxy-o-mentha-1(7),4,8-triene; the chirality has been confirmed as 2 R, 3 S by correlation with the (-)-cis-o-menthane obtained from carquejol and that from (+)-verbenene of known absolute configuration.The two double bonds of the dihydrocarquejol system (15 and 16) constitute a helical system, that especially in the case of the acetate (16) fixes the isopropenyl group in such a way that a very high Δ∊ value in the CD. curve is observed. The conformational significance of this phenomenon is discussed.
