Ni- and Cu-Catalyzed Coupling Reactions Using 2-(4,5-Dihydro-1H-imidazo-2-yl)phenol as a Versatile Phosphine-Free Ligand
摘要:
We have disclosed 2-(4,5-dihydro-1H-imidazo-2-yl)phenol (1) worked efficiently as a ligand in Ni-catalyzed Suzuki-Miyaura coupling reactions and Cu-catalyzed N-cyclopropylation of indoles using cyclopropylboronic acid.

Structure-Based Design of the Indole-Substituted Triazolopyrimidines as New EED–H3K27me3 Inhibitors for the Treatment of Lymphoma
Interrupting the embryonic ectoderm development (EED)–H3K27me3 interaction represents a promising strategy to allosterically inhibit polycomb repressive complex 2 (PRC2) for cancer therapy. In this work, we report the structure-based design of new triazolopyrimidine-based EED inhibitors, which structurally feature the electron-rich indole ring at the C8 position. Particularly, ZJH-16 directly binds
