Inverse Phase Transfer Catalyst

An environmentally benign, scalable and highly selective C-arylalkylation of active methylene compounds is developed using CTAB as the inverse phase transfer catalyst. The methodology is also applicable to the regioselective synthesis of N-aralkyl/alkyl 2-pyridones.

Dihydropyridine Derivatives

Dipyrimidine-fused pyridine derivatives were synthesized using 1,3-diketone, aldehyde, different ammonium salts, and water, as the solvent. Aromatization was observed when ammonium nitrate was used as the source of nitrogen, and thus, dipyrimidine-fused pyridine derivatives were synthesized in one-pot synthetic procedure. This environmentally benign procedure leads to high yield of products (80%–90%) in a single step, with greater purity using water as the solvent.Key words: water, aromatization, dipyrimidopyridine, ammonium salts.
