Pd-Catalyzed Coupling of Thioamides with N-Tosylhydrazones/Trapping by Esters Cascade Reaction

N,N-Disubstituted thioamides coupled with N-tosylhydrazones under Pd(TFA)2/tBuXPhos catalyst and NaOtBu, and the intermediates from palladium carbene migratory insertion containing β-hydrogen were trapped by intramolecular esters activated by BF3·Et2O ins

Copper(I)/Bpy-Catalyzed C-2-H Benzylation of Quinazolin-4(3H)-ones with N-Tosylhydrazones

A general and efficient copper-catalyzed C–H benzylation reaction of quinazolin-4(3H)-ones with N-tosylhydrazones is reported. The formation of new C(sp3)–C(sp2) bonds through cross-coupling occurs at the electron-poor C-2 position of quinazolin-4(3H)-one and represents an exceedingly practical method to afford 2-benzylated quinazolin-4(3H)-ones in moderate to good yields under mild reaction conditions. A possible reaction mechanism for this transformation was proposed. This catalytic transformation has the potential to be an important synthetic application for the late-stage functionalization of advanced synthetic intermediates.

I2-Promoted [4 + 2] cycloaddition of: In situ generated azoalkenes with enaminones: Facile and efficient synthesis of 1,4-dihydropyridazines and pyridazines

A facile and efficient strategy for the synthesis of 1,4-dihydropyridazines and pyridazines through I2-promoted [4 + 2] cycloaddition of in situ generated azoalkenes with enaminones has been developed. The switch in selectivity is attributed to the judici
