A Rh(III)-catalyzed bilateral cyclization was developed for the efficient construction of acridines proceeding with C–H functionalization whereby in situ formation and removal of an imino transient directing group in the presence of catalytic amount of BnNH2 are achieved. In this transformation, a sequential Rh(III)-catalyzed C–H amination, cyclization, and aromatization process was involved.
开发了Rh(III)催化的双环环化反应,可有效构建–啶并进行C–H官能化,从而在催化量的BnNH 2存在下原位形成和去除亚氨基瞬态导向基团。在此转化过程中,涉及到了连续的Rh(III)催化的CH–H胺化,环化和芳构化过程。
