Compounds of the present invention are useful for inhibiting protein tyrosine kinases. Also disclosed are methods of making the compounds, compositions containing the compounds, and methods of treatment using the compounds.
A hydrogenbonddonorsolvent assisted (radio)halogenation and deuteration of organoborons has been developed. The reactions exhibited high functional group tolerance and needed only an ambient atmosphere. Most importantly, compared to literature methods, our conditions are more consistent with the principals of green chemistry (e.g., metal‐free, strong oxidant‐free, more straightforward conditions)
The first example of palladium-catalyzed direct formylation of arylzincreagents using S-phenyl thioformate is reported. The reaction proceeded undermildconditions, allowing high functional group tolerance. In addition, the developed formylation method was used to prepare deuterated and 13C-labeled aryl aldehydes from isotope-labeled S-phenyl thioformates. Moreover, this procedure was applied to

An iron-catalyzed cascade reaction of radical reduction of allyl alcohols and acetylenic acids to construct polysubstituted α-alkenyl lactones has been developed. In this paper, various allyl alcohols can form allyl ester intermediates and are further transformed into alkyl radicals, which form products through intramolecular reflex-Michael addition. In addition, this method can be used to prepare
