发展了一种铑催化的3-乙烯基吲哚与芳基三氮唑的环合反应。通过优化催化剂、反应温度、时间和eq.比等反应条件,最终在氩气保护下,以2.5 mol% Rh2(OAc)4为催化剂,1,2-二氯乙烷为溶剂,3-乙烯基吲哚和芳基三氮唑的eq.比为1/2时,60 ℃反应6~12h,一步合成了15个新型的3-(2,3-二氢吡咯)吲哚衍生物(3aa~3al, 3ba~3da),其结构经1H NMR,13C NMR和HR-MS(ESI)表征。

The interaction of Cu^2+ complex of N,N'-bis(2-aminoethyl)-2,6-pyridinedicarboxamide (BAP) with DNA was studied by agarose gel electrophoresis analysis. The results indicate that the BAP-Cu^2+ complex can promote the cleavage of phosphodiester bond of supercoiled DNA at physiological condition, which is 3.2 × 10^6 times higher than DNA natural degradation. A hydrolytic cleaving mechanism through the cooperation of copper ions and functional amino groups was proposed. 相似文献
