Chlorophthalazines were efficiently metalated using tmpZnClËLiCl under microwave irradiation. This provided novel substituted phthalazine derivatives after subsequent trapping of the resulting organometallic reagents with various electrophiles. Moreover, Negishi cross-coupling reactions have been performed affording new polyfunctionalized phthalazine scaffolds in very good yields.
氯代苯氮杂环在微波辐射下有效地进行了
金属化,使用了tmpZnCl·LiCl。随后与各种电亲核试剂捕获反应,得到了新型取代的苯氮杂环衍
生物。此外,Negishi交叉偶联反应也已执行,产生了新的多功能化苯氮杂环骨架,并且产率非常好。
