Synthesis of various 6-substituted 1,4,5,6-tetrahydropyridazines by substitution of a 1,4,5,6-tetrahydro-6-tosylhydrazinopyridazines

Diastereoselective synthesis of functionalized tetrahydropyridazines containing indole scaffolds via an inverse-electron-demand aza-Diels–Alder reaction

A base-promoted and catalyst-free unprecedented inverse-electron-demand aza-Diels–Alder reaction between the in situ generated azoalkenes and 3-vinylindoles has been developed to afford tetrahydropyridazines containing indole scaffolds.

Mechanisms of phosphine-catalyzed [3+3] cycloaddition of ynones and azomethine imines: a DFT study

Mechanisms of PPh₃-catalyzed [3+3] cycloaddition between a ynone and an azomethine imine.

5-Methylene N-acyl dihydropyridazinium ions as novel Mannich-type acceptors in 1,4 additions of nucleophiles

Mannich-type addition reactions of various type of nucleophiles with N-acyliminium ions, generated in situ from 5-methylene-6-methoxy-1,4,5,6-tetrahydropyridazines, in the presence of BF₃·OEt₂, have been developed.
