Cyclisation of the tandem conjugateaddition products 1-3 by displacement of either the OH or SPh group provides a short efficient synthesis of lignanlactones including compounds of the clinically important podophyllotoxin series.

The synthesis of (±)-epiisopodophyllotoxin commencing with 6-bromopiperonal dimethyl acetal is described. The carbon skeleton of isoepipodophyllotoxin was assembled via a Diels–Alder reaction between the hydroxyquinodimethane generated photochemically from 6-(3′,4′,5′-trimethoxybenzyl)-piperonal, obtained from the bromoacetal above, and dimethyl fumarate. This Diels–Alder adduct was converted in five
