Synthesis.
A 2-pyridyl-alkylation of benzyne using N-alkylpyridinium salts has been developed under either photochemical or thermal conditions. This metal-free dicarbofunctionalization of benzyne undergoes a de Mayo-type process including cascade dearomative [3

Thanks to the facile imine-enamine tautomerization, the β,γ-unsaturated hydrazones have been successfully utilized as surrogates of aminodienes for realizing the Pd-catalyzed tandem aminomethylamination/aromatization reaction with aminals via C-N b
