A Tetrazine‐Based Synthesis for Accessing Underutilized Aza‐Indole Analogues

Chemistry – A European Journal, Volume 31, Issue 25, May 5, 2025.
A nucleophilic aromatic substitution (SNAr)/Diels–Alder (DA)/retro Diels–Alder (rDA) reaction cascade has been developed to access pyrazolo[3,4‐c]pyridazine compounds. These cores have been further derivatized through divergent, late‐stage modifications to access various substitution patterns of the 3, 4, and 5 positions on the heterocyclic core ...
