Podophyllotoxin is probably the most prominent representative of lignan natural products. Deoxy-, epi-, and podophyllotoxin, which are all precursors to frequently used chemotherapeutic agents, were prepared by a stereodivergent biotransformation and a biocatalytic kinetic resolution of the corresponding dibenzylbutyrolactones with the same 2-oxoglutarate-dependent dioxygenase. The reaction can be conducted on 2 g scale, and the enzyme allows tailoring of the initial, “natural” structure and thus transforms various non-natural derivatives. Depending on the substitution pattern, the enzyme performs an oxidative C?C bond formation by C?H activation or hydroxylation at the benzylic position prone to ring closure.

Deoxypodophyllotoxin is a secondary metabolite lignan possessing potent anticancer activity with potential as a precursor for known anticancer drugs, but its use is limited by scarcity from natural sources. We here report the total synthesis of racemic de

A series of aryltetralin lignans 7a, 7b, 7c, 7d, 7e, 7f, 7g, 7h, 7i, 7j, 7k, 7l were synthesized as cytotoxic isodeoxypodophyllotoxin analogs. The title compounds 7a, 7b, 7c, 7d, 7e, 7f, 7g, 7h, 7i, 7j, 7k, 7l were synthesized from the reaction of (+)-(R)-4-[benzo(d)(1,3)dioxol-5-ylmethyl]-dihydrofuran-2-(3H)-one with different arylaldehydes to afford benzyl alcohol analogs and subsequent cyclization with trifluoroacetic acid in dichromethane. The preliminary screening of the compounds against viability of blood cancer human cell line K562 revealed that compounds 7d, 7e, and 7f had higher inhibitory activity at 10 μg/mL concentration compared with etoposide as reference drug.
