Four New Dibenzocyclooctene Lignans from Kadsura renchangiana
Authors:Min Chen  Zhixin Liao  Daofeng Chen
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.
