The Biology - Chemistry Interface: A Tribute To Koji Nakanishi
We have assigned the absolute stereochemistry of ( + )-1,8a-dihydro-3,8-
dimethylazulenc [( + )-1] isolated from a liverwort, a labile intermediate on the
biosynthetic pathway to 1 ,4-dimethy lazulene (2), as (8aS) by the application of
this ...

A Fragrant Introduction to Terpenoid Chemistry
However, the stereochemical ingenuity of this synthesis arises from the fact that
the only centre which is not easily isomerised is that carrying the methyl group,
and this centre is now fixed in the correct absolute stereochemistry for /-menthol.

Measurement of the optical rotation of the cleavage products then can be used to
define the absolute stereochemistry. The majority of condensed tannins (such as
conifer bark or wattle tannins) are of a 2R absolute stereochemistry. Quebracho ...

Bioactive Natural Products (Part G)
In this study, the CD spectra of two neolignans, one possessing a 7-S, 8-S
absolute stereochemistry (96) and the other a 7-R, 8-R absolute stereochemistry
(97), were compared with the CD spectra of gnetins F-I (47-50). In each case, the

absolute stereochemistry all show a strong positive couplet whilst those related to
procyanidins B-3 (80, catechin- (4ot- »8)-catechin) or B-4 (83, catechin-(4a- »8)-
epicatechin) with 45- absolute stereochemistry) exhibit a negative couplet.
