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.
copper‐catalyzed cross‐coupling of 1,2‐dihaloalkenes and amides leads to cyclic β‐haloenamides, which can participate in a second cross‐coupling reaction to efficiently synthesize highly functionalized cyclic enamides. The selectivity of the intramolecular coupling between exo‐ and endocyclic regioisomers is a crucial synthetic factor and can be influenced by the structure of the substrate and the reaction conditions

molecules with novel skeletons, but also to identify the enzymes that catalyze diverse chemical reactions. Exploring the substrate promiscuity and catalytic mechanism of those biosynthetic enzymes facilitates the development of potential biocatalysts. SfaB is an acyladenylate‐forming enzyme that adenylates a unique building block, 3‐isocyanobutanoic acid, in the biosynthetic pathway of the diisonitrile
8-naphthyridin-2(1H)-ones have been synthesized with the inverseelectron-demandDiels-Alderreaction from 1,2,4-triazines bearing an acylamino group with a terminal alkyne side chain. Alkynes were first subjected to the Sonogashira cross-coupling reaction with aryl halides, the product of which then underwent an intramolecularinverseelectron-demandDiels-Alderreaction to yield 5-aryl-3,4-dihydro-1,8-naphthyridin-2(1H)-ones

Born to couple: The Pd(OAc)2‐catalyzed reaction of o‐alkynylanilines (1) with o‐alkynylbenzamides (2) affords the cyclizative cross‐coupling products 3 in good to excellent yields. Three bonds are created in the formation of two heterocycles tethered by a tetrasubstituted double bond. Mechanistic studies indicate that the reaction is initiated by aminopalladation with subsequent oxypalladation, N‐demethylation
