Multilinker phosphorous acid anchored En/MIL-100(Cr) as a novel nanoporous catalyst for the synthesis of new N-heterocyclic pyrimido[4,5-b]quinolines

Recent applications of aminouracil in multicomponent reactions

“…85 In 2017, Sepehrmansouri et al synthesized a variety of functionalized pyrimido [4,5-b]quinolone derivatives in high yields at reflux conditions (Scheme 32). 86 They prepared a novel ethylenediamine (En) based metal-organic frameworks (MOFs) of Cr-MOFs, En/MIL-100(Cr), and containing phosphorous acid tags, and applied for Knoevenagel-Michael condensation reaction the synthesis of new series of N-heterocyclic compounds. For preparing MIL-100(Cr)/NHEtN(CH2PO3H2)2 as the MOF catalyst, they used the condensation reaction of MIL-100(Cr)/NHEtNH2, paraformaldehyde, phosphorous acid, hydrochloric acid, and EtOH as solvent under reflux condition.…”

“…Synthesis of pyrimido [4,5-b]quinolone derivatives using MIL-100(Cr)/NHEtN(CH2PO3H2)2. 86 Mirhosseini-Eshkevari and co-workers 871 developed an excellent strategy for preparing pyrimido [4,5d]pyrimidines (59), using TEDA-BAIL@UiO-66, a novel catalyst, in EtOH under ultrasound irradiation with high yields. Privileged structures useful in medicinal chemistry were obtained.…”

Novel nano-architectured carbon quantum dots (CQDs) with phosphorous acid tags as an efficient catalyst for the synthesis of multisubstituted 4H-pyran with indole moieties under mild conditions

“…14 Materials with phosphorous acid tags have been introduced as catalysts, adsorbents, inhibitors and extractants. 15 Recently a wide variety of solid acid catalysts with phosphorous acid functional groups, such as glycoluril, 16 SBA-15, 17 a melamine-based nano catalyst, 18 metal-organic frameworks (MOFs) [19][20][21] and uric acid, 22 have been reported for the synthesis of organic compounds.…”

Fe3O4@MCM‐41@ZrCl2: A novel magnetic mesoporous nanocomposite catalyst including zirconium nanoparticles for the synthesis of 1‐(benzothiazolylamino)phenylmethyl‐2‐naphthols

“…In spite of significant advances in the field of mesoporous materials and the growing expansion of new types of them, [1][2][3][4][5][6][7][8] the first and foremost member of M41S called MCM-41 still has attracted growing research attention owing to its chemical versatility. [9][10][11][12][13] Its capabilities, especially in the field of catalytic activity, all come from its unique properties, such as high surface area ($1000 m 2 g −1 ), narrow pore size distribution, uniform pore size, and the possibility of adjusting the diameter of the pores between 2 and 10 nm.…”
