In this study, two brucine derivative were synthetized; in first stage, the compound 1-phenyl-[2-(2,3-dimethoxystrychnidin-10-yldeneamino)-ethylamino]-methyl}-naphtalen- 2-ol (4) was development by the reaction of b-naphthol, N1-(2,3-dimethoxystrychnidin-10-yliden)-ethane-1,2-diamine and benzaldehyde in ethanol. Also 4 was prepared by the reaction of brucine with 1-[(2-amino-ethylamino)-phenyl-methyl]-naphthalen-2-ol using as catalyst boric acid. In the second stage, the compound 4-hydroxy-N-[2-(2,3-dimethoxystrychnidin-10-ylideneamino)-ethyl]benzamide (8) was synthetized by the reaction of 4-hydroxybenzoic acid with N1-(2,3- dimethoxystrychnidin-10-yliden)-ethane-1,2-diamine using a carbodiimide derivative as catalyst. Finally, in other experiment the compound 8 was also prepared by the reaction of brucine with N-(2-aminoethyl)-4-hydroxybenzamide in presence of a carbodiimide derivative. The structure of all compounds obtained was confirmed by elemental analysis and spectroscopic methods.
本研究合成了两种马钱子碱衍生物;第一阶段,通过b-萘酚反应生成化合物1-苯基-[2-(2,3-二甲氧基番木素-10-亚基氨基)-乙基氨基]-甲基}-萘-2-醇(4), N1-(2,3-二甲氧基马钱子素-10-亚基)-乙烷-1,2-二胺和苯甲醛的乙醇溶液。 4还通过使用硼酸作为催化剂,使马钱子碱与1-[(2-氨基-乙基氨基)-苯基-甲基]-萘-2-醇反应来制备。第二阶段,由4-羟基苯甲酸与N1-(2,使用碳二亚胺衍生物作为催化剂,得到3-二甲氧基马钱子(10-亚基)-乙烷-1,2-二胺。最后,在其他实验中,也通过马钱子碱与N-(2-氨基乙基)-4-羟基苯甲酰胺在碳二亚胺衍生物存在下反应制备了化合物8。所获得的所有化合物的结构均通过元素分析和光谱方法进行了确认。
