were synthesized by several routes starting from natural α-amino esters 2 and o-haloaryl- or o-bromohetarylmethyl bromides 1. N-Alkylation of the starting amino esters to 5 and 3 was followed by halogen/lithium exchange and double cyclization. The cyclization products 6 exhibit interesting inhibition of RNase H and DNA-polymerase activity of reverse transcriptase (RT) of HIV-1 at concentrations where
从天然α-氨基酯2和邻-卤代芳基-或邻-溴代杂芳基甲基溴化物1开始,通过多种途径合成了1-氮杂双环[3.3.1]壬烷6。然后将起始氨基酯N-烷基化为5和3通过卤素/锂交换和双环化。在人类细胞 DNA 聚合酶不受影响的浓度下,环化产物 6 表现出对 RNase H 和 HIV-1 逆转录酶 (RT) 的 DNA 聚合酶活性的有趣抑制。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2004)
