The decarbonization of lignan a and dihydroindene b were synthesized through α-asarone by acid-catalyzed. Compounds a/b were identified by 1H NMR, 13C NMR, MS and elemental analysis. The effects of catalysts, solvents and temperature on yields of a/b have been evaluated. The total yield of a/b reached 98% (a: 41%, b: 57%) with HCl as catalyst and ethanol as solvent at 45 ℃. The yield of compound a was up to 75% with AlCl3 as catalyst and ethanol as solvent at 30 ℃, b was not formed in this condition, and the selectivity of a was 100%. When using BF3·Et2O as catalyst and methylene chloride as solvent at 45 ℃, the yield of compound a was 20% and b was formed in yield of 60%. The cytotoxic activities of two compounds against MCF-7, Bel-7402, A549 and Hela were evaluated in vitro by the MTT assay. The results indicated that compounds a/b exhibited better cytotoxic activities against four cancer cells than 5-Fu. Especially, the IC50 values of a to MCF-7 and Hela reached 120.2 and 117.3 μmol·L-1 as well as the IC50 of b to MCF-7 and A549 reached 66.1 and 72.4 μmol·L-1, respectively. At the same time, the concentration of a/b and time of operation to influence inhibitory activity were explored.

Key words: dihydroindene, decarbonization of lignan, selectivity, anticaner activity
