New approach in total synthesis of indole alkaloids was invented using carbohydrates. Stereocontrolled 15α-H and 15β-H derivatives such as 26a,b and 30a,b were obtained using the same sugar 24. A pure 3α-H, 15α-H compound 32a,b was also prepared an acyliminium intermediate in a Pictet-Spengler condensation with tryptamine.
使用碳水化合物发明了吲哚生物碱全合成的新方法。使用相同的糖24获得立体控制的15α-H和15β-H衍生物,例如26a,b和30a,b。还通过与色胺的Pictet-Spengler缩合反应制备了纯的3α-H,15α-H化合物32a,b。
