A fluorous, cyclative-capture strategy based on a new Pummerer cyclization process allows rapid access to tagged, heterocyclic frameworks. Convenient modification of the fluorous, heterocyclic scaffolds by using a variety of approaches including Pd-catalyzed cross-couplings is possible. Traceless, reductive cleavage of the fluorous-phase tag or oxidative cleavage and further elaboration, completes
基于新的Pummerer环化过程的氟代循环捕获策略可快速访问带标签的杂环框架。通过使用包括Pd催化的交叉偶联在内的多种方法,可以方便地修饰氟杂环骨架。氟相标签的无痕还原裂解或氧化裂解并进一步完善,完成了各种N杂环化合物高通量氟相合成的策略。
