In this paper, the synthesis of bi- and trisubstituted indazoles was described. 4-Alkoxy-7-aminoprotected-indazole or 7-aminoprotected-indazole derivatives were prepared selectively using SnCl2 in alcohol or SnCl2 in ethyl acetate, respectively. The effects of the halogen atom in position 3 and of the N-alkylation in N-1 position of 7-nitroindazoles were investigated.
在本文中,描述了双取代和三取代的吲唑的合成。4-烷氧基- 7- aminoprotected吲唑或制备7- aminoprotected吲唑衍生物选择性地使用的SnCl 2在醇或的SnCl 2分别在乙酸乙酯中,。研究了7-硝基吲唑的3位卤素原子和N -1位N-烷基化的影响。
