Unprecedented imidazo[1,2-a]thiochromeno[3,2-e]pyridines have been synthesized via a three-component cascade reaction under solvent-free conditions. This one-pot transformation involving multiple steps and not requiring the use of transition metal catalysts constructs three new C–C bonds, two C–N bonds, one C–S bond, and three new rings with all reactants efficiently utilized.
前所未有的咪唑并[1,2- a ]硫代色素[3,2- e ]吡啶已通过三组分级联反应在无溶剂条件下合成。这种一锅转化涉及多个步骤,不需要使用过渡金属催化剂,可以构建三个新的C–C键,两个C–N键,一个C–S键和三个新的环,并有效利用所有反应物。
