Indoles are a significant heterocyclic system in natural products and drugs. They are
important types of molecules and natural products and play a main role in cell biology. The …

Both polycyclic pyrimidin-4-one synthesis and the dehydrogenative coupling of malonates
often require a redox agent, an elevated temperature, large amounts of transition-metal …

Abstract A [4+ 2]‐cycloaddition of para‐quinone methides with hexahydro‐1, 3, 5‐triazines is
reported. The reaction occurs under very mild conditions (catalyst‐, ligand‐, and base‐free) …
