Garcinol, isolated from the fruit rind of Garcinia indica, shows anti-carcinogenic and anti-inflammatory activities. However, the C(8) side chain of garcinol is so large that it may influence the bioactivity of the compound. 8-Allyl garcinol, in which the bulky side chain at C(8) position of garcinol is replaced with much smaller allyl group, was synthesized through a 12-step procedure. Starting from 1,3-cyclohexandione, the key intermediate (±)-1-hydroxy-5,5-dimethyl-4,6-bis(3-methylbut-2-en-1-yl)bicyclo[3.3.1]non-2-ene-3,9-dione (8) was obtained via Effenburger cyclization. Through additional 5-steps, 8-allyl garcinol was prepared. The thiazolyl blue tetrazolium bromide (MTT) results indicated that 8-allyl garcinol shows strong inhibitory activity on cell proliferation of oral cancer cell lines.

Key words: garcinol, Effenburger cyclization, synthesis, structural modification
