Contrasting Reactivity of 2-Mesityl-1,8-Naphthyridine (Mes-NP) with Singly-Bonded [Rh-II-Rh-II] and [Ru-I-Ru-I] Compounds

Reaction of cis-[Rh-2(CH3COO)(2)(CH3CN)(6)](BF4)(2) with two equivalents of 2-mesityl-1,8-naphthyridine (Mes-NP) affords trans-[Rh-2(CH3COO)(2)(Mes-NP)(2)](BF4)(2) (1). X-ray structure reveals weak Rh-C(ipso) interaction, and a short Rh-Rh distance. The same ligand, in contrast, oxidatively cleaves the Ru-Ru bond in cis-[Ru-2(CO)(4)(CH3CN)(6)](BF4)(2) and results in trans-[Ru(Mes-NP)(2)(CH3CN)(2)](BF4)(2) (2). Both compounds adopt trans geometry to relieve the steric strain. Compound 2 exhibits moderate activity for the alcohol oxidation and aldehyde olefination reactions.

The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 99-55-8, in my other articles. Application In Synthesis of 2-Methyl-5-nitroaniline.

Design, Synthesis, and Pharmacological Evaluation of Novel 2-(4-substituted piperazin-1-yl)1, 8 Naphthyridine 3-Carboxylic Acids as 5-HT3 Receptor Antagonists for the Management of Depression

1, 8-naphthyridine-3-carboxylic acid analogs were synthesized and found to possess potential 5-HT3 receptor antagonism as well as antidepressant-like activity. Initially, 5-HT3 receptor antagonism of all the compounds was determined in the form of pA(2) value against agonist 2-methyl 5-HT in longitudinal muscle-myenteric plexus preparation from guinea-pig ileum. Among all the compounds tested, compound 7a demonstrated most promising pA(2) value of 7.6. Subsequently, all the compounds were evaluated for antidepressant activity using forced swim test and tail suspension test in mice. Compounds 7a, 7d, 7f, 7h, and 7i exhibited significant (p<0.05) antidepressant-like activity as compound to vehicle-treated group. Importantly, none of the tested compound affected locomotor activity of mice at tested dose levels. The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.Welcome to check out more blogs about 92-70-6, in my other articles.

Regioselective Synthesis of Benzo[h][1,6]- naphthyridines and Chromenopyrazinones through Alkyne Cyclization

A regioselective approach to the synthesis of benzo[h][1,6]-naphthyridine and chromenopyrazinone derivatives was developed. The synthetic route to benzo[h][1,6]naphthyridines involves the N-propargylation of aromatic aminobenzaldehydes, followed by reaction with propargylamine in the presence of DBU (1,8-diazabicyclo[5.4.0] undec-7ene). For the synthesis of chromenopyrazine and chromeno-pyrazinone derivatives, the acetonitrile group was introduced to salicylaldehyde derivatives, and a DBU-promoted cyclization reaction between aldehydes and propargylamine gave the chromenopyrazines. The intramolecular heterocycloaddition reaction between the triple bond and the azadiene, which is formed as an intermediate, gave the desired structures.

Self-Assembled Cagelike Receptor That Binds Biologically Relevant Dicarboxylic Acids via Proton-Coupled Anion Recognition

We report here a fully organic, self-assembled dimeric receptor, constructed from acyclic naphthyridyl-polypyrrolic building blocks. The cagelike dimer is stable in the solid state, in solution, and in gas phase, as inferred from X-ray diffraction and spectroscopic analyses. This system acts as a receptor for oxalic acid, maleic acid, and malonic acid in the solid state and in THF solution. In contrast, acetic acid, propionic acid, adipic acid, and succinic acid, with pK(a) values > ca. 2.8, were not bound effectively within the cagelike cavity. It is speculated that oxalic acid, maleic acid, and malonic acid serve to protonate the naphthyridine moieties of the host, which then favors binding of the corresponding carboxylate anions via hydrogen-bonding to the pyrrolic NH protons. The present naphthyridine- polypyrrole dimer is stable under acidic conditions, including in the presence of 100 equiv trifluoroacetic acid (TFA), p-toluenesulfonic acid (PTSA), H2SO4, and HCI. However, disassembly may be achieved by exposure to tetrabutylammonium fluoride (TBAF). Washing with water then regenerates the cage. This process of assembly and disassembly could be repeated >20 times with little evidence of degradation. The reversible nature of the present system, coupled with its dicarboxylic acid recognition features, leads us to suggest it could have a role to play in effecting the controlled capture and release of biologically relevant dicarboxylic acids.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states.

Synthesis of the Azaoxoaporphine Alkaloid Sampangine and Ascididemin-Type Pyridoacridines through TMPMgCl center dot LiCl-Mediated Ring Closure

We report the synthesis of the azaoxoaporphine alkaloid sampangine (4) and a series of ring A analogues and isomers of the marine pyridoacridine alkaloid ascididemin (2). This approach starts from readily available 1-bromo[2,7] naphthyridine (12) or 4-bromobenzo[c][2,7] naphthyridine (5), and the ring A scaffold bearing an ester moiety is introduced by a Suzuki or Negishi cross-coupling reaction. The final cyclization step was achieved through a directed remote ring metallation with the Knochel-Hauser base (TMPMgCl center dot LiCl; TMP = 2,2,6,6-tetramethylpiperidinyl), followed by intramolecular trapping of the ester group.

A novel ratiometric fluorescent probe based on coumarin derivative for the recognition of Al(III) and its application on test strips

A novel ratiometric probe (L) which was composed of chromone and coumarin moieties has been designed and synthesized for sensing Al3+ in EtOH in view of the internal charge transfer (ICT) mechanism. The free probe L exhibited a strong fluorescence emission at 477 nm, and the fluorescence emission here almost disappeared after adding Al3+ (10 equiv.) while a new peak appeared at 524 nm. This may be due to the enhancement of intramolecular electron transfer efficiency from donor to acceptor. In addition, this probe L could be form a 1:1 complex with Al3+, which could be explained by the ESI-MS spectra, and L had a low detection limit for Al3+ with a binding constant of 1.32 x 10(4) M-1 More importantly, L could be applied to a solid probe for rapid detection of Al3+ with a significant color change.
