and a half-chair of ring C, as well as α-oriented substituted groups N…Me, C…Me, and C…OH is revealed. Feeding experiments with cell suspension cultures of Corydalis incisa (Papaveraceae) defined the intermediacy of (−)-corycavinium in the route from protoberberine-type to hexahydrobenzo[c]phenanthridine-type of alkaloids. On the basis of the present crystal conformation, the stereospecificity of the
已经通过X射线分析研究了(-)-椰油英鎓(+)-10-樟脑磺酸盐的晶体结构。(-)-corycavinium离子((-)-(7 S,13 S,14 R)-5,6,13,13a-四氢-13a-羟基-7-甲基-2,3; 9,10的结构已经确定了-双(亚甲基二氧基)-8 H-二苯并[ a,g ]喹啉鎓。与B / C-顺式连接点,B环的扭曲半椅和C环的半椅以及带有α取向的取代基N…Me,C…Me和C…OH的构型是揭示了。延胡索细胞悬浮培养的饲养实验罂粟科(Papaveraceae)定义了从小ine碱型到六氢苯并[ c ]菲啶型生物碱的途径中(-)-corycavinium的中间体。基于当前的晶体构象,从生物学上考虑了相关酶的立体特异性。
