2-Hydroxypyrrolo[2,1-c][1,4]benzodiazepines were aromatised in refluxing thionyl chloride into 11-chloropyrrolo[2,1-c][1,4]benzodiazepines in high yield. This aromatic system is doubly reactive towards nucleophiles leading to rearranged products such as iminobenzoxazines and quinazolines.
2-羟基吡咯并[2,1- c ^ ] [1,4]苯并二氮杂类中在回流的亚硫酰氯为11个氯吡咯芳香烃[2,1- c ^ ] [1,4]高收率苯二氮。该芳族体系对亲核试剂具有双反应性,从而导致重排产物,如亚氨基苯并恶嗪和喹唑啉。
