A fragment library of electrophilic small heterocycles was characterized through cysteine-reactivity and aqueous stability tests that suggested their potential as covalent warheads.
of 2‐vinyl nitrogen‐containing heteroaromatic compounds with styrylboronicacid in the presence of a cobalt catalyst and a base results in an addition reaction to afford the corresponding 4‐phenyl‐3‐butenyl heteroarenes. The adjacent nitrogen atom is essential for the promotion of the reaction because the nitrogen accelerates the addition of the styryl cobalt species, generated by transmetalation, onto

transducer and activator of transcription-3 (STAT3) signaling pathway inhibitory activity, shows significant inhibitory activity against several tumors. In this study, a series of ICTS derivatives and simplified analogs containing a 1, 4-naphthoquinone core was designed, synthesized, and evaluated. The results demonstrated that most target compounds were potent STAT3 signaling pathway inhibitors based
A novel regio- and stereoselective reductive coupling of vinyl azaarenes and alkynes has been developed to access functionalized azaarene compounds bearing stereodefined tri-substituted alkenes via photoredox cobalt dualcatalysis. Simple organic base together with alcohol has been applied as the hydrogen sources instead of commonly used Hantzsch esters in this coupling reaction.
