The pyrrolo[2,1-c][1,4]benzoxazine system was synthesized from 2-fluoroaniline involving an intramolecular nucleophilic displacement of the fluoride atom. The intermediate alcohols 7a and 10 were treated in basic media under strictly controlled conditions which led to the desired tricyclic structure. The unsubstituted alcohol 10 was more stable than the substituted one.
由涉及氟原子的分子内亲核取代的2-氟苯胺合成吡咯并[ 2,1- c ] [1,4]苯并恶嗪系统。在碱性介质中,在严格控制的条件下处理中间体醇7a和10,得到所需的三环结构。未取代的醇10比取代的醇更稳定。
