A novel route to a common intermediate for the synthesis of both cuparane and herbertane sesquiterpenoids involves de novo construction of the aromatic ring by an intramolecular Diels-Alder reaction.

Cyclisation of the L,D- and L,L-O-methyltyrosyl-p-nitrophenylalanine methyl esters is studied; in the presence of beta-cyclodextrin, reaction took place only with the L,L-isomer.

Phenolic sesquiterpenes including sesquichamaenol, 6-(2-hydroxy-4-methylphenyl)-2-methyl-3-beptanone, and curcuphenol methyl ether have been obtained from oxidative cleavage of bicyclic precursors by treatment with acidic hydrogen peroxide in a process which probably parallels a biogenetic step A ketone intermediate for curcudiol has also been acquired in the same manner.
SYNTHETIC STUDIES TOWARDS FAVELINE METHYL-ETHER

A convergent approach to faveline methyl ether based on Claisen rearrangement is delineated Thus the benzylic and allylic alcohol substrate was assembled by a Grignard reaction, and the rearrangement product was oxidized and cyclized. Double bond isomers of faveline methyl ether were obtained.
