M-Menthane

The menthane-type radicals given below are based on the p-form of menthane. Names of the radicals derived from the few known o- and m-menthane-type mono-eye lies would be analogous. The established fixed numbering for p-menthane is shown on the formula for p-menthyl the position numbers in all of the recommended radical names are based on this numbering. The names in parentheses shown below some of the recommended names are the common terpene radical names. Examples ... [Pg.80]

Thymol Derivatives.-—Occurrence. Several new thymol derivatives have been obtained from a variety of plant species 870-871 isolation of (263) from roots of a Marshallia sp. was claimed to have chemotaxonomic significence.872 Isothymol (m-menthane skeleton) and its esters occur naturally 873-874 a phenolic ether... [Pg.66]

Verghese has published a review about this class. Authentically naturally occurring m-menthanes are m-thymol (687, R = H) and its methyl ether 687 (R = Me), isolated from various Calea species as well as the isobutyl ether 687 (R = iBu) from Athrixia elata. Paknikar has synthesized 687 (R = H) by Grignard reaction of 2-hydroxy-5-methylacetophenone. ... [Pg.391]

The cis- and trans-m-menthanes (40,41) have been prepared by way of thermal cleavage of cis- and trans-A -carenQ (equations 22 and 23) °. The models of optical activity so... [Pg.165]
