The preparation of N-containing functionalized porous organic polymers for selective synthesis of C3-alkylated indoles and triazine derivatives

“…13 Recently, we synthesized several nitrogen-containing heterocycle-based catalysts which displayed some catalytic reactivity in the borrowing hydrogen and dehydrogenation reactions. 14,15 However, a limitation of these catalysts was that reactions with the C3-alkylated indoles and triazine derivatives were unsuccessful, which indicated that it is necessary and urgent to develop efficient and highly active catalysts. Herein, we synthesized a pyridine and pyrazole-based porous organic polymer (Py-POP) and its corresponding metal polymer Ru@Py-POP, which could be used to catalyze the reactions of indoles with alcohols and biguanides with alcohols (Scheme 1).…”

Photocatalytic Pyridine Synthesis with Enaminones and TMEDA under Metal-Free Conditions

“…Pyridine is a fundamental heterocyclic motif with prevalent presence in molecules associated with human life such as pharmaceuticals, materials, as well as synthetic building blocks . In addition, the pyridines have also been found to possess various other functions such as acting as an organic base, a ligand, as well as single-electron donors . Being inspired by the important applications of pyridine scaffolds, the synthesis of pyridine keeps attracting extensive interest from chemical and related other communities.…”
