2-Substituted 1-tosyl-3,4,4-trimethylimidazolidines prepared by the addition of anions to 1-tosyl-3,4,4-trimethyl-2-imidazolinium iodide 1, react with tryptamine in the presence of acetic acid to give 1-substituted β-carboline derivatives. The salt 1 reacts with anions of 2-[2-(1,3-dithianyl)]benzoates 4a-c to give the corresponding imidazolidines 5a, 5b and 5c, respectively. These transfer the substituted
2-取代的加入阴离子的制备1-甲苯磺酰基-3,4,4-三甲基-2-咪唑啉鎓碘化物1-甲苯磺酰基-3,4,4- trimethylimidazolidines 1,与色胺在乙酸的存在下反应得到的反应1-取代的β-咔啉衍生物。盐1与2- [2-(1,3-二硫代烷基)]苯甲酸酯的阴离子4a-c反应,分别得到相应的咪唑烷5a,5b和5c。这些将取代的片段转移到色胺中,得到对应于育亨宾骨架的五环产物。从5c得到的产物,在酰胺和二噻吩官能团均降低后,生成了表育和异代育亨宾的前体。
