indoloberbine ring skeletons is reported. Treatment of heterocyclic bases such as isoquinolines, phthalazines, and ellipticine with 2-chloromethylbenzoyl chloride and trimethylsilyl cyanide gave the corresponding Reissert compounds. Treatment of these Reissert compounds with sodium hydride resulted in intramolecular cyclization with loss of hydrogen cyanide.
报道了一种新的合成方法,用于构建贝宾,6-阿扎贝宾和吲哚贝宾环环骨架。用2-氯甲基苯甲酰氯和三甲基甲硅烷基氰化物处理杂环碱,例如异喹啉,酞嗪和玫瑰树碱,得到相应的Reissert化合物。用氢化钠处理这些Reissert化合物会导致分子内环化,并损失氰化氢。
