  Synthesis of novel polyazadipyridinocyclophane scaffolds and their application for the generation of libraries

  摘要：

  Six novel, asymmetric, 19- to 26-membered polyazadipyridinocyclophane scaffolds 1-6 have been synthesized in high yields by an efficient cyclization of ditosylate 39 with the appropriate six fully protected triamines 40-45, followed by removing the 2-nitrobenzenesulfonyl protecting groups. intermediate 39 was synthesized by the Mitsunobu reaction of 2-nitrobenzenesulfonamide (37) with 2,6-pyridinedimethanol (36), and a subsequent tosylation of the resulted diol 38. The fully protected asymmetric triamines 41 and 43 were prepared from the corresponding commercially available triamines 52 and 53. A new synthetic route was developed for the synthesis of the protected asymmetric triamines 44 and 45. Ah reactions were carried out at room temperature in high yields. The reaction of t-Boc-protected scaffold 1, having three reactive sites, with nine benzylic bromides and bromoacetonitrile, using a solution phase simultaneous addition of functionalities combinatorial strategy, Save t-Boc-protected library 7 containing 1000 compounds. Deprotection of library 7 generated the intermediate library 8 with one reactive site. Subsequent reactions at the unsubstituted position of 8 with various functionalities by four types of reactions gave sixteen final libraries 9-24. Libraries 7-24 have different functionalities at the fixed position, and each of them contains 1000 compounds. The reaction of scaffold 2, having four reactive sites without protecting groups, with six sets of polar functionalities afforded eleven diverse libraries 25-35 containing 625 compounds in each library. Totally, twenty-nine libraries containing 24875 compounds were obtained. Eight libraries exhibited antibacterial activity against Escherichia coli imp(-) and Streptococcus pyogenes with the MIC's of 2 to 10-50 mu M. Seven libraries disrupted HIV-1 tat/TAR protein-RNA interactions with IC50's as low as 0.08 mu M. (C) 1998 Elsevier Science Ltd.All rights reserved.
