Karrer and Enslin reported that the structure of alstyrine (S_(19)H_(22)N_2), a selenium- dehydrogenation-degradation product obtained by Sharp from the alkaloid alstonine, is identical with that of corynanthyrine, α-[2-(4, 5 diethylpyridyl)]-β-ethylindole (Ⅱ), despite the fact that the melting points of these two substances have a 5°difference. In his investigation, the author of the present paper has synthesized two homologues of (II), α-(2-pyridyl)-β- methylindole (Ⅲ) and α-(2-pyridyl)-β-ethylindole...

Karrer and Enslin reported that the structure of alstyrine (S_(19)H_(22)N_2), a selenium- dehydrogenation-degradation product obtained by Sharp from the alkaloid alstonine, is identical with that of corynanthyrine, α-[2-(4, 5 diethylpyridyl)]-β-ethylindole (Ⅱ), despite the fact that the melting points of these two substances have a 5°difference. In his investigation, the author of the present paper has synthesized two homologues of (II), α-(2-pyridyl)-β- methylindole (Ⅲ) and α-(2-pyridyl)-β-ethylindole (Ⅳ), finding that the former has almost the same ultraviolet absorption spectrum as that of alsyrine and that, like alstyrine, the metho- sulphate of the compounds (Ⅲ) and (Ⅳ) gives the same red colour reaction upon treatment with dilute sodium-hydroxide solution. The Fischer indole synthesis to cyclize the phenylhydrazone of the corresponding alkyl- 2-pyridylketone in the presence of mineral acid was employed by the author in the preparation of compounds (Ⅲ) and (Ⅳ). Besides, three a-carboline derivatives, namely, 2-(cyclohexylmethyl)-β-carboline (Ⅻ), 2-[(4'-methylcyclohexyl)-methyl]-β-carboline (XIII) and 2-[(2'-methylcyclohexyl)-methyl]- β-carboline (XIV), have also been synthesized; none of them is identical with alstyrine in physical and chemical properties. The preparation of compounds (Ⅻ), ((XIII)) and ((XIV)) was carried out according to the method originated by Bischler and Napieralski. This involved the condensation of tryptamine with a suitable acid, or acid chloride, first to form an amide, which was then cyclized with phosphorus pentoxide, and finally dehydrogenated .partially with selenium. The melting points of the two α-(2-pyridyl)-β-alkylindoles, three β-carbolines, their inter- mediates, and a few derivatives of theirs are as follows: ■

1.合成了兩種吲(口朶) 衍生物:α-(2-吡啶基)-β-甲基吲(口朶) 及α-(2-吡啶基)-β-乙基吲(口朶)。前者的紫外線吸收光譜與阿爾斯泰令(alstyrine,係一種由西阿斯木鹼經硒降解後的產物)的吸收光譜極為類似;且二者有一種相同的顏色反應。因此說明阿爾斯泰令的結構可能與可利南斯令(corynanthyrine),α-[2-(4,5-雙乙吡啶基)]-β-乙基吲(口朶)相同。 2.合成了三種β-咔卟啉的衍生物:2-環己烷甲基-β-咔卟啉,2-[(4′-甲基環己烷)甲基]-β-咔卟啉及2-[(2′-甲基環已烷)甲基]-β-咔卟啉。這些化合物的化學及物理性質都和阿爾斯泰令不同。因此後者不是β-咔卟啉衍生物。

With the action of phase transfer catalyst(PTC),2-methylindole was N-alky-lated.The effects of different PTC,reacting time,temperature,the concentration of potassium hydroxide and the bromoethane amout on the reaction were studied.The selection of N,C-alkylation was explained theoretically. The relationship of concentration and structures of the catalyst to the reacting rate have been studied quantitatively.
