Kadsurenin M (7s, 8s- 3, 4, 3'- trimethoxy- 7'- o\o- nor-8', 9'-7. O, 4' - 8, 5'-neolingan)(1), a benzofuranoid neolignan isolated tyom the aerial part of Piper Kadsura (Choisy) Ohwi,was synthesized in 6 steps from vanillin via a key intermediate 3,4- dimethoxycinnamyl (2'-methoxy- 4'- formyl)phenyl ether (7). The overall yield is 15%.
