摘要 4-β-Cyano-4-deoxy-4'-demethylepipodophyllotoxin 4 was synthesized from 4'-de -methylepipodophyllotoxin and Me3SiCN in the presence of BF3· Et2O. 4-β-Carboxyl-4-deoxy-4'-demethylepipodophyllotoxin 5 was obtained by hydrolyzing 4 in HOAc. Both of them show very high anticancer activities against L1210 and KB cell lines in vitro. 4-β-Cyano-4-deoxy-4'-demethylepipodophyllotoxin 4 was synthesized from 4'-de -methylepipodophyllotoxin and Me3SiCN in the presence of BF3· Et2O. 4-β-Carboxyl-4-deoxy-4'-demethylepipodophyllotoxin 5 was obtained by hydrolyzing 4 in HOAc. Both of them show very high anticancer activities against L1210 and KB cell lines in vitro.
