The macrocyclic diamides 11–21, 42 and 43 were prepared by nucleophilic reaction of the bis phenols 22–29 with the appropriate dihalo compounds 2, 3, 40 and 41, respectively. The macrocyclic dithiodiamides 30–33 were obtained in good yields upon treatment of 11, 13, 15 and 17 with Lawesson's reagent. The macrocycles 61–63 were prepared by condensation of the bis(aldehyde) 37 with the appropriate bis(aminotriazoles)
大环二酰胺11 - 21,42和43是由双酚的亲核反应而制备22 - 29用适当的二卤代化合物2,3,40和41分别。大环dithiodiamides 30 - 33在处理后的良好的产率得到11,13,15和17与Lawesson试剂。大环61 – 63是通过双(醛)缩合制备的37用适当的双(氨基三唑)50 – 54生成相应的席夫碱56 – 60,然后用NaBH 4还原。
