胡 涛,殷跃凡,张海波 (扬子江药业集团有限公司,江苏 泰州 225321)
摘 要:以1-金刚烷甲醇(1)为起始原料,经PCC氧化得1-金刚烷甲醛(2),随后经维悌希反应引入醛基得2-(1-金刚烷基)乙醛(3)、经与苄胺、氰基三甲基硅烷通过改进的斯特雷克反应一锅法生成α氨基腈(4)、再经水解成酰胺(5),脱去苄基得到α氨基酰胺(6)、最后在盐酸作用下水解成盐得标题化合物2-氨基-3-(1-金刚烷基)丙酸盐酸盐(TM),共6步反应,总收率为23%,其结构经1H NMR和MS进行确证。

Abstract:Using PCC as the catalyst, (adamantan-1-yl)methanol(1)was oxidized into adamantane-1-carbaldehyde(2) and then 2-(adamantan-1-yl)acetaldehyde(3) was obtained via Witting reaction of 2 with (methoxymethyl)triphenylphodphonium chloride. α-Aminonitrile(4) was obtained through an improved one-pot Strecker reaction of 3 with benzylamine and trimethylsilanecarbonitrile. α-Aminoamide (6) was obtained through a series of reactions of 4 including hydrolysis, de-benzyl via hydrogenolysis catalyzed by Palladium/carbon. Finally, the title compound, 3-(adamantan-1-yl)-2-aminopropanoic acid hydrochloride was produced by the acidic hydrolysis of 6 using hydrochloride acid with a total yield of 23% and its structure was confirmed by 1H NMR and MS.
Key words:(adamantan-1-yl)methanol; witting reaction; trimethylsilanecarbonitrile; strecker reaction; one-pot
