A method for the preparation of pyrimido[1,2-a]benzimidazoles containing a 2-hydroxybenzyl or (2-hydroxynaphthalen-1-yl)methyl group at position 3 was proposed based on the reaction of β-carbonyl-substituted 4H-chromenes and their benzo analogs with 2-aminobenzimidazole. In the case of chromenes substituted in the methylene fragment, 7,13a-dihydro-5H-benzo[5′,6′]chromeno-[3′,2′:5,6]pyrimido[1,2-a]benzimidazoles were isolated.

Recommanded Product: 1H-Benzo[d]imidazol-2-amine. The article was titled 《A unique benzimidazole-naphthalene hybrid molecule for independent detection of Zn2+ and N-3 ions: Experimental and theoretical investigations》. The information in the text is summarized as follows:

Single crystal X-ray structurally characterized benzimidazole-naphthalene hybrid (NABI) functions as a unique dual analyte sensor that can detect Zn2+ cation and N-3 anion independently. The NABI forms chelate with Zn2+ to inhibit internal charge transfer (ICT) and -CH=N- isomerization resulting chelation enhanced fluorescence (CHEF). On the other hand, the sensing of N-3 is based on formation of supramol. H-bonded rigid assembly. The association constant of NABI for Zn2+ and N-3 ions are 19 × 104 M-1 and 11 × 102 M-1, resp. Corresponding limit of detections (LOD) are 6.85 × 10-8 and 1.82 × 10-7 M, resp. NABI efficiently detects intracellular Zn2+ and N-3 ions with no cytotoxicity on J774A.1cells under fluorescence microscope. DFT studies unlock underlying spectroscopic properties of free NABI and Zn2+/N-3 bound forms.

Recommanded Product: 1H-Benzo[d]imidazol-2-amine The author mentioned the following in the article:

Target-response deformation has provided a wide variety of possibilities for selective mol. separation In this report, both exptl. and theor. methods were used to demonstrate how fine-tuning the amphiphilicity of ZIF-7 can induce an alc.-based target-response deformation. A step-by-step simulation of dynamic adsorption revealed that ZIF-7-NH2 can successfully align alc. mols. to facilitate selective adsorption, while the benzene rings in ZIF-7-NH2 were induced to flip over and maintain the open-gate conformation. As a result, ZIF-7-NH2 with an amino mole ratio of 10% achieved an ideal n-butanol/water selectivity of 40, and also the highest n-butanol uptake of 4.33 mmol g-1 from 5 wt% n-butanol aqueous solution under ambient conditions. Therefore, a new mechanism of “”Induced-Fit Suction”” (IFS) that we propose provides a promising new strategy for biofuel separation After reading the article, we found that the author used 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7Recommanded Product: 1H-Benzo[d]imidazol-2-amine)

《Degradation kinetics of carbendazim by Klebsiella oxytoca, Flavobacterium johnsoniae, and Stenotrophomonas maltophilia strains》 was written by Alvarado-Gutierrez, Maria Luisa; Ruiz-Ordaz, Nora; Galindez-Mayer, Juvencio; Curiel-Quesada, Everardo; Santoyo-Tepole, Fortunata. HPLC of Formula: 934-32-7 And the article was included in Environmental Science and Pollution Research in 2020. The article conveys some information:

The fungicide carbendazim is an ecotoxic pollutant frequently found in water reservoirs. The ability of microorganisms to remove pollutants found in diverse environments, soil, water, or air is well documented. Although microbial communities have many advantages in bioremediation processes, in many cases, those with the desired capabilities may be slow-growing or have low pollutant degradation rates. In these cases, the manipulation of the microbial community through enrichment with specialized microbial strains showing high specific growth rates and high rates and efficiencies of pollutant degradation is desirable. In this work, bacteria of the genera Klebsiella, Flavobacterium, and Stenotrophomonas, isolated from the biofilm attached to the packed zones of a biofilm reactor, were able to grow individually in selective medium containing carbendazim. In the three bacteria studied, the mheI gene encoding the first enzyme involved in the degradation of the fungicide carbendazim was found. Studying the dynamics of growth and carbendazim degradation of the three bacteria, the effect of co-formulants was also evaluated. The pure compound and a com. formulation of carbendazim were used as substrates. Finally, the study made it possible to define the biokinetic advantages of these strains for amendment of microbial communities. In the experimental materials used by the author, we found 1H-Benzo[d]imidazol-2-amine(cas: 934-32-7HPLC of Formula: 934-32-7)

Recommanded Product: 934-32-7In 2021 ,《Using sulfate-functionalized Hf-based metal-organic frameworks as a heterogeneous catalyst for solvent-free synthesis of pyrimido[1,2-a]benzimidazoles via one-pot three-component reaction》 was published in Journal of Industrial and Engineering Chemistry (Amsterdam, Netherlands). The article was written by Dinh Dang, Minh-Huy; Ho Thuy Nguyen, Linh; Thi Thu Nguyen, Trang; Xuan Dat Mai, Ngoc; Hoang Tran, Phuong; Le Hoang Doan, Tan. The article contains the following contents:

In this work, a sulfate-functionalized Hf-cluster-based metal-organic framework was prepared via sulfation of a Hf-MOF, named Hf-BTC, constructed by Hf6 clusters and 1,3,5-tricarboxylate linkers. The Hf-BTC-SO4 material was consequently demonstrated to be an efficiently reusable superacid catalyst for a one-pot three-component reaction of pyrimido[1,2-a]benzimidazoles synthesis. The reaction catalyzed by the sulfated Hf-BTC could be carried out under mild and solvent-free conditions and give superior performance in a wide range of substrates. According to detailed investigation, the good catalytic performance of the sulfated-functionalized MOF likely originates from the high-porosity framework and the high active sites of the functionalized clusters. Importantly, the catalyst was easy to recover and reuse the functionalized framework several times with minor changes in catalytic efficiency.
