A new synthesis of 6-carbomethoxy-1,2,3,5-tetrahydroirnidazo[2,3-b][1,3]benzodiazocines 13 by the intramolecular cycloaddition reaction of methyl 2-(1-aziridinylmethyl)-3-(2-ureidophenyl)propenoates 10 under Appel's dehydration conditions is described. The latter were readily obtained from 2-nitrobenzalde-hyde with methyl acrylate through the Baylis-Hillman reaction.
通过2-(1-叠氮基甲基)-3-甲基的分子内环加成反应合成6-carbomethoxy-1,2,3,5-tetrahydroirnidazo [2,3- b ] [1,3] benzodiazocines 13描述了在Appel的脱水条件下的-脲基苯基)丙烯酸酯10。后者很容易通过Baylis-Hillman反应从2-硝基苯甲醛与丙烯酸甲酯中获得。
