Novel self-condensation of 3-(azol-5-yl)-1,1-dimethylenamines has been found to form new C–C bonds leading to 2,4-(1,2,3-triazole-1,2,3-thiadiazole-3-phenylisothiazole)-(1E,3Z)-5-yl-butadiene-1-amines. The discovered reaction represents a new example of C–H functionalization in unsaturated systems and can serve an efficient synthetic approach to rational design of new 2,4-(diazole-5-yl)-dieneamines
已发现3-(azol-5-yl)-1,1-二甲基亚胺的新型自缩合形成新的C–C键,从而导致2,4-(1,2,3-三唑-1,2,3 -噻二唑-3-苯基异噻唑)-(1 E,3 Z)-5-基丁二烯-1-胺。所发现的反应代表了不饱和体系中C–H官能化的新实例,可为合理设计新的2,4-(二唑-5-基)-二烯胺提供有效的合成方法。
