Abstract The structures of agrostonin and agrostonidin, two new dimeric phenanthrene derivatives isolated from the orchids, Agrostrophyllum khasiyanum and A. callosum , were established as 2,2′,7,7′-tetramethoxy-1,1′-biphenanthryl, respectively, from spectral and chemical evidence, including regioselective biomimetic synthesis from their respective 9,10-dihydro monomers by oxidative coupling with phosphomolybdic
摘要 从兰花中分离的两种新的二聚菲衍生物 Agrostrophyllum khasiyanum 和 A. callosum 的 agrostonin 和 agrostonidin 的结构分别为 2,2',7,7'-四甲氧基-1,1'-联菲基。光谱和化学证据,包括通过与硅胶表面上的磷钼酸 (PMA) 氧化偶联从它们各自的 9,10-二氢单体进行区域选择性仿生合成。
