divergent transformation of 2-amino-1,4-quinones for the synthesis of pyrroquinone derivatives and 2-halo-3-amino-1,4-quinones was disclosed. The mechanistic study showed that both the tandem cyclization and halogenation involved a Cu(I)-catalyzed oxidative radical process. This protocol not only constructed a series of novel pyrroquinone derivatives with high atom economy but also provided a new method
公开了用于合成吡咯醌衍生物和2-卤代-3-氨基-1,4-醌的2-氨基-1,4-醌的发散转化。机理研究表明串联环化和卤化均涉及Cu(I)催化的氧化自由基过程。该方案不仅构建了一系列具有高原子经济性的新型吡咯醌衍生物,而且提供了一种以 CuX (X = I , Br, Cl) 作为 X (X = I、Br、Cl) 来源。

A number of 5H-Benzo[b]naphtho[2,3-d]pyrrole-6,11-dionederivatives were synthesized. Their biologicalactivity was compared with that of the corresponding benzoxazolo- and benzthiazolo-analogues.
