A synthesis of four 1H-[1,2]diazepino[4,5-b]indole derivatives and some preliminary information about their biological activity are presented. The starting materials were 2-ethoxycarbonylindoles and 2-ethoxy-carbonyl-3-formylindoles, la, b and 2a, b, respectively. 2-Ethoxycarbonyls la, b reacted with 1-dimethylamino-2-nitroethylene and -2-ethoxycarbonyl-3-formylindoles 2a, b in the presence of nitroalkanes
介绍了四种1 H- [1,2]二氮杂[4,5- b ]吲哚衍生物的合成及其生物学活性的一些初步信息。起始原料分别是2-乙氧基羰基吲哚和2-乙氧基羰基-3-甲酰基吲哚,1a,b和2a,b。2-乙氧基羰基1a,b在硝基烷烃(硝基甲烷或硝基乙烷)的存在下与1-二甲氨基-2-硝基乙烯和-2-乙氧基羰基-3-甲酰基吲哚2a,b反应,得到3-(2-硝基乙烯基)吲哚3a,b。还原3a,b得到β-(2-氧代烷基)吲哚4。与过量的水合肼反应时,化合物4产生令人满意的5-oxo-1 H- [1,2]二氮杂ino [4,5- b ]收率。吲哚5。
