The conjugate addition-alkylation to 5H-furan-2-one followed by cyclization and controlled epimerizations have been applied to the synthesis of new furo- and thieno-lignan analogues. Podophyllotoxin and thuriferic acid heteroanalogues have been obtained by this methodology, as representative members of these families. (C) 2001 Elsevier Science Ltd. All rights reserved.
Synthesis and cytotoxic activities of analogues of thuriferic acid
Several analogues of thuriferic acid and derivatives, with the 3,4-methylenedioxyphenyl ring replaced by naphthalene, furan, thiophene and carbazole ring systems, have been prepared. The synthetic strategy is based on a conjugate addition alkylation methodology followed by cationic cyclization in order to obtain the isopodophyllone analogues, which are transformed in the thuriferic acids. Their cytotoxic activities against several tumour cells lines are also described. (C) 2001 Elsevier Science Ltd. All rights reserved.
