Abstract: | Four new dibenzocyclooctene‐type lignans, named renchangianins A–D ( 1 – 4 ), were isolated from the stems of Kadsura renchangiana. Their structures and configurations were elucidated by spectroscopic methods, including 2D‐NMR techniques. Renchangianin D ( 4 ) possesses a spiro[dibenzocyclooctene‐6,2′‐oxirane] parent structure previously unknown in plants of the Schisandraceae family. |
