, p. 3201 - 3206 (2008/04/01)
A concise, seven step synthesis of the aryl tetralin lignan lactone epi-picropodophyllin from piperonal is described. The key steps are a silene diene Diels-Alder reaction and the Hosomi-Sakurai reaction of the resultant silacyclohexene. The Royal Society

The 2-benzopyran-3-one 10 is a stable, isolable and useful Diels-Alder diene; its methyl 4-benzoyloxycrotonate adduct 23 formed regioselectively and stereoselectively in acetonitrile is reduced with H2/Pd to give 31 with inversion of C-1 stereochemistry.T
