The Batcho–Leimgruber strategy was employed to synthesize 3-(2-dimethylamino-[2H4]-ethyl)-1H-indol-5-ol (bufotenine, 5-HO-DMT) (8) from commercial 3-methyl-4-nitro-phenol (1), benzyl bromide and N,N–dimethylformamide–dimethylacetal. Compound 4 was synthesized from compound 3 using the Batcho–Leimgruber strategy in the presence of Raney nickel and hydrazine hydrate. Compound 4 was treated with oxalyl chloride, dimethylamine and lithium aluminum [2H4]-hydride to yield [2-(5-benzyloxy-1H-indol-3-yl)-[2H4]-ethyl]-dimethyl-amine (7). The benzyl ether in compound 7 was cleaved by hydrogenolysis to give bufotenine 8. Copyright © 2007 John Wiley & Sons, Ltd.
采用 Batcho-Leimgruber 策略,以商用 3-甲基-4-硝基苯酚 (1)、溴化苄和 N,N-二甲基甲酰胺-二甲基乙缩醛为原料,合成 3-(2-二甲基氨基-[2H4]-乙基)-1H-吲哚-5-醇(布福替宁,5-HO-DMT)(8)。化合物 4 是在雷尼镍和水合肼存在下,采用巴乔-莱姆格鲁伯(Batcho-Leimgruber)策略从化合物 3 合成的。化合物 4 经草酰氯、二甲胺和铝锂[2H4]-酸酐处理后得到[2-(5-苄氧基-1H-吲哚-3-基)-[2H4]-乙基]-二甲基-胺(7)。化合物 7 中的苄基醚通过氢解作用裂解,得到布福滕宁 8。Copyright © 2007 John Wiley & Sons, Ltd.
