Synthesis and reactivity of 6-carbamoyl-5-phenyl-2,3,5,6-tetrahydro-1H-1,4-ethanobenzo[f]quinoline. X-Ray molecular structure of (4aR,5S,6R,10bR)-5-phenyl-2,3,4a,5,6,10b-hexahydro-1H-1,4-ethanobenzo[f]quinolin-6-yl acetate
phenylation instead of lactam formation. The cyclic product was hydrogenated to give 6-carbamoyl-5-phenyl-2,3,4a,5,6,10b-hexahydro-1H-1,4-ethanobenzo-[f]quinoline. On treatment with LiAlH4 the carbamoyl group was stereospecifically replaced by a hydroxy group. The alcohol was acetylated and the structure was confirmed by X-ray crystallography. The hydroxylation reaction is believed to proceed via a
在硫酸存在下2-(2-氰基-1,2-二苯基乙基)奎宁环酮-3-酮1的环缩合得到分子内苯基化而不是内酰胺的形成。将该环状产物氢化,得到6-氨基甲酰基-5-苯基-2,3,4a,5,6,10b-六氢-1 H -1,4-乙基苯并-[ f ]喹啉。用LiAlH 4处理时,氨基甲酰基被立体定向地替换为羟基。将该醇乙酰化,并通过X射线晶体学确认结构。认为羟基化反应是通过甲腈中间体进行的。在空气存在下,腈可以转化为酮,然后将其还原为醇,并保持整体构型。
