Nanoporous AlSBA-15 catalysts with different nSi/nAl ratios (41, 129, and 210) were synthesized using a hydrothermal method. These catalysts were characterized by XRD, N2 sorption, TPD-NH3, FT-IR, SEM and TEM. XRD analyses of AlSBA-15 catalysts confirmed the presence of well-ordered crystalline structure with p6mm symmetry. The sp. surface area and specific pore volume of the AlSBA-15 catalysts are in the range of 480 to 757 m2/g and 0.65 to 0.95 cm3/g, resp. The catalytic performance of nanoporous AlSBA-15 catalysts are used as an outstanding catalytic system for one-pot synthesis of α-aminophosphonates via Kabachnik-Fields reaction in a three-component system using amines (primary/secondary), carbonyl compounds (aldehydes/ketones) and di-Et phosphite. The major advantages of the present contributions are excellent yields, short reaction time, simple exptl. technique, high chemo-selectivity, catalyst recyclability, easy work-up procedure and green approach. Three-component synthesis of α-aminophosphonates follows first imine formation from amine and aldehyde/ketone followed by phosphate addition The exptl. findings suggest that the nanoporous AlSBA-15 catalysts can be recycled and reused up to six cycles without any loss in the catalytic performance. In the experiment, the researchers used many compounds, for example, 2-Methoxypyrimidine-5-carbaldehyde (cas: 90905-32-1Product Details of 90905-32-1).
2-Methoxypyrimidine-5-carbaldehyde (cas: 90905-32-1) belongs to pyrimidine derivatives. Heterocyclic compounds bearing the pyrimidine core are of tremendous interest as they constitute an important class of natural and synthetic compounds exhibiting diverse useful biological activities that hold attractive potential for clinical translation as therapeutic agents in alleviation of a myriad of diseases. As nucleotides in DNA and RNA, pyrimidine nucleotide derivatives have a wide range of biological applications. For example, pyrimidine derivatives are useful in DNA repair studies involving cancer and epigenetics.Product Details of 90905-32-1
