Two practical routes for the synthesis of benzhydrylamine derivatives in enantiomerically pure form have been developed. N-Acetylbenzhydrylamines can be synthesised in few steps and good yields starting from 1-aryl-1-propargylamines. The key steps are represented by the alkene-alkyne cross metathesis reaction and alkyne–diene methylene-free tandem-metathesis reaction; these reactions have been performed
已经开发了两种合成对映体纯形式的二苯甲基胺衍生物的实用路线。N-乙酰二苯甲基胺可以从 1-芳基-1-炔丙基胺开始,通过几个步骤和良好的产率合成。关键步骤以烯烃-炔烃交叉复分解反应和炔-二烯无亚甲基串联复分解反应为代表;这些反应是在微波辐射下在几分钟内完成的,产率很高。N-乙酰二苯甲基胺也被转化为抗真菌剂联苯苄唑的两种对映异构体,强调了这些化合物作为合成对映纯形式的生物活性化合物的支架的重要性。 (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim,德国,2007)
