Synthesis of podophyllum lignan analogues

Three polophyllotoxin analogues 1-3 having unsymmetrically substituted methoxyl groups in the pendant aryl ring have been synthesized by the application of tandem conjugate addition reaction.Piperonal propane-1, 3-dithiane, but-2-en-4-olide and 2, 3, 4-tr

Simple Synthesis of Furanoid and Dioxabicyclooctane Lignans

The key intermediates, the keto lactones 5, 6 obtained by convergent synthesis, were transformed into furanoid and dioxabicyclooctane lignan analogues 7, 8 by means of sodium borohydride reduction and subsequent acid-catalysed cyclisation.
