Cativic acid

The absolute configurations of sclareol (2) and manool (5), Fig. (7), at C-13 have been determined [133]. As Hanson reported [134], the absolute stereochemistry assigned to some labdanes should be reexamined due to the enantiomers of labdanes. The biosynthetic pathways of sclareol and manool start from a geranyllinalool - type skeleton which cyclizes in a similar fashion as that described for cativic acid [135] and, via the intermediate 6, Fig. (7), sclareol is formed by hydration of 6, or manool by the loss of a proton [112,136]. [Pg.254]

Labdanum gum and concrete contain volatile oil, paraffins, and resins. The resins consist of acidic constituents (e.g., labdanolic acid, 6-oxo-cativic acid, cinnamic acids, anisic acid, arachic acid, behenic acid butyric, malo-nic, and oxalic acids) and neutral labdane compounds (e.g., labdane-8a,15-diol, labdane 8a,15,19a-triol, 15-nor-8-labdanol, labd- 8(17)-en-15-ol, and 15-hydroxy-7-lab-... [Pg.404]
