Anatabine is obtained by reacting benzophenoneimine with 3-aminomethyl pyridine to form benzylhydrylidene-pyridin-3-yl-methyl-amine. The benzylhydrylidene-pyridin-3-yl-methyl-amine is treated with a non-nucleophilic base and a dielectrophile, such as cis-1,4-dichloro-2-butene, followed by acidification, then basification, to provide anatabine. The resulting anatabine is substantially free from contaminants and displays good stability. In an alternative embodiment, the benzylhydrylidene-pyridin-3-yl-methyl-amine may be used in the synthesis of other alkaloids such as anabasine, nornicotine, N-methylanabasine, and anabaseine.
Anatabine是通过将苯甲酮亚胺与3-氨甲基吡啶反应形成苄基亚胺基吡啶-3-基-甲胺而获得的。将苄基亚胺基吡啶-3-基-甲胺与非亲核碱和双电子亲合剂(如顺-1,4-二氯-2-丁烯)反应,然后经过酸化、碱化处理,得到Anatabine。所得的Anatabine基本上不含杂质,并具有良好的稳定性。在另一种实施方式中,苄基亚胺基吡啶-3-基-甲胺可用于合成其他生物碱,如阿那巴碱、诺尼古丁、N-甲基阿那巴碱和阿那巴西。
