This paper reports the use of p-phenylenediamine to prepare bis-Troger’s bases. The methyl,nitro-substituted bis-Troger’s base 5, already previously prepared by another procedure, was obtained in fewer steps, although with no improvement in the yield of the desired syn isomer. The symmetric dinitro-substituted bis-Troger’s base 17, which cannot be prepared by the older method, was then synthesized
本文报道了使用对苯二胺制备双特罗格碱。甲基、硝基取代的双-Troger's 碱 5 已经通过另一个程序预先制备,以更少的步骤获得,尽管所需顺式异构体的产率没有提高。然后合成了不能通过旧方法制备的对称二硝基取代的双特罗格碱 17。其结构通过质谱法、2D NMR 光谱法确定,并且在顺式异构体的情况下,通过 X 射线晶体学确定。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
