The synthesis of stemofurans C, L and T was achieved using organomanganese arene complexes. The critical carbon-carbon bond between the C-2 position of benzofuran and the arene was established in a regioselective manner directed by the cationic manganese tricarbonyl moiety. Oxidation of the resulting dienyl complexes and cleavage of the methyl ethers gave the desired stemofuran products. The spectroscopic
使用有机锰芳烃配合物可以合成茎呋喃C,L和T。苯并呋喃的C-2位与芳烃之间的关键碳-碳键是以阳离子选择性的三羰基锰锰部分指导的区域选择性方式建立的。所得二烯基复合物的氧化和甲基醚的裂解得到所需的呋喃呋喃产物。最初提议的呋喃呋喃L结构的光谱数据与合成材料不匹配,这促使合成了确实与光谱数据匹配的异构体。有人提议将这种修订后的结构作为木茎呋喃L的正确结构。
