The article was titled 《1-Arylvinyl formates: A New CO Source and Ketone Source in Carbonylative Synthesis of Chalcone Derivatives》. The information in the text is summarized as follows:

1-Arylvinyl formates as a kind of new CO surrogate was explored for the first time. Most of the known CO precursors usually produced undesired residuals, which were to be removed. In this strategy, after CO release, the in-situ generated acetophenones from 1-arylvinyl formates were successfully applied as a good ketone source in the synthesis of chalcones with benzaldehydes via a palladium-catalyzed reductive carbonylation reaction. A variety of chalcones were isolated in satisfactory to good yields with good substrates compatibilities under mild conditions.1-Iodo-2-methoxybenzene(cas: 529-28-2Safety of 1-Iodo-2-methoxybenzene) was used in this study.

1-Iodo-2-methoxybenzene(cas: 529-28-2) is a useful synthetic intermediate. It can be used in the synthesis of piperidinyl diaminopyrimidines as cyclin-dependent kinase inhibitors with antitumor activity and polysubstituted benzofuran derivatives as novel inhibitors of parasitic growth.Safety of 1-Iodo-2-methoxybenzene

Using eugenol and vanillin as model substrates, a practical method is developed for the cleavage o-hydroxyphenyl alkyl ethers. Aluminum oxide iodide (O=AlI), generated in situ from aluminum triiodide and DMSO, is the reactive ether cleaving species. The method is applicable to catechol monoalkyl ethers as well as normal Ph alkyl ethers for the removal of Me, Et, iso-Pr, and benzyl groups. A variety of functional groups such as alkenyl, allyl, amide, cyano, formyl, keto, nitro, and halogen are well tolerated under the optimum conditions. Partial hydrodebromination was observed during the demethylation of 4-bromoguaiacol, and was resolved using excess DMSO as an acid scavenger. This convenient and efficient procedure would be a practical tool for the preparation of catechols. The experimental process involved the reaction of m-Methoxyphenol(cas: 150-19-6Related Products of 150-19-6)

Li, Yuwen; Li, Sen; Du, Xin; Gu, Zhongze published an article in 2021. The article was titled 《Disulfide-yne reaction: controlling the reactivity of a surface by light》, and you may find the article in RSC Advances.Electric Literature of C12H10S2 The information in the text is summarized as follows:

In this paper we provide new insight into the disulfide-yne photo reaction, which is similar but different from the well-known thiol-yne photoclick reaction. We show that, unlike the stable product generated from thiol-yne chem., the vinyl dithioether structure obtained from disulfide-yne reaction exhibits unique reactivity with thiols and disulfides, which can be used for surface photochem. to fabricate reactive and dynamic surfaces. The possible mechanism for the unique reactivity of vinyl dithioether structure was discussed. We demonstrated that disulfide-yne reactions are highly compatible with thiol-yne chem., but offer the flexibility and dynamic nature that is lacking in thiol-yne chem., thus could be a good replenishment for the existing thiol-yne toolbox.1,2-Diphenyldisulfane(cas: 882-33-7Electric Literature of C12H10S2) was used in this study.

The ZnFe2O4@alginic acid nanocomposite was synthesized by a simple procedure. Then, it was utilized as a green, cost-effective and heterogeneous catalyst in the synthesis of 2-amino-3-cyano-4H-pyran derivatives I (R = H, 2-NO2, 3-MeO, 4-OH, etc.) with a one-pot three-component reaction between various aromatic aldehydes RC6H4CHO, dimedone and malononitrile.

A three-step sequence for preparing remdesivir, an important anti-SARS-CoV-2 drug, is described. Employing N,N-dimethylformamide di-Me acetal (DMF-DMA) as a protecting agent, this synthesis started from (2R,3R,4S,5R)-2-(4-aminopyrrolo[2,1-f][1,2,4]triazin-7-yl)-3,4-dihydroxy-5-(hydroxymethyl)tetrahydro-furan-2-carbonitrile (GS-441524) and consisted of three reactions, including protection, phosphoramidation, and deprotection. The advantages of this approach are as follows: (1) the protecting group could be removed under a mild deprotection condition, which avoided the generation of the degraded impurity; (2) high stereoselectivity was achieved in the phosphorylated reaction; (3) this synthesis could be performed successively without purification of intermediates. Moreover, the overall yield of this approach on a gram scale could be up to 85% with an excellent purity of 99.4% analyzed by high-performance liquid chromatog. (HPLC).

Safety of Bis(4-methoxyphenyl)amineIn 2019 ,《Introduction of Fluorine Into spiro[fluorene-9,9′-xanthene]-Based Hole Transport Material to Obtain Sensitive-Dopant-Free, High Efficient and Stable Perovskite Solar Cells》 was published in Solar RRL. The article was written by Guo, Kunpeng; Wu, Min; Yang, Shaomin; Wang, Zongtao; Li, Jie; Liang, Xiaozhong; Zhang, Fang; Liu, Zhike; Wang, Zhongqiang. The article contains the following contents:

Despite the substantial development of efficient hole transporting materials (HTMs) for high-performance perovskite solar cells (PSCs), optimization of the HTMs to sensitive-dopant-free HTMs for high efficient PSCs with prominent stability have rarely been reported. Herein, a low-cost fluorinated spiro[fluorene-9,9′-xanthene] based HTM termed 2mF-X59 is designed and synthesized. In comparison with its reported nonfluorinated counterpart X59, 2mF-X59 shows lowered HOMO (HOMO) level, improved hole mobility, and hydrophobicity. Aided by 2,3,5,6-tetrafluoro-7,7,8,8-tetracyanoquinodimethane (F4TCNQ) to further lower the HOMO level of 2mF-X59 and improve its hole transfer, the optimized 2mF-X59 based PSCs show a maximum power conversion efficiency (PCE) of 18.13% without the use of any sensitive-dopants (e.g., lithium salt/4-tert-butylpyridine), which is comparable to the Spiro-OMeTAD based PSCs (18.22%) with sensitive dopants. More importantly, the sensitive-dopant-free 2mF-X59 based PSCs maintain 95% of their initial performance for more than 500 h under air exposure, showing much better long-term stability than control PSCs based on Spiro-OMeTAD with sensitive dopanst. This is the first case that a sensitive-dopant-free HTM is demonstrated in PSCs with a high PCE (>18%) and good stability by optimizing the literature HTM. This work could pave a new way to develop low-cost sensitive-dopant-free HTMs for highly efficient and stable PSCs for practical applications. In the experiment, the researchers used Bis(4-methoxyphenyl)amine(cas: 101-70-2Safety of Bis(4-methoxyphenyl)amine)

The compound bridge methylene tacrine (BMT) was synthesized, which has the classical pharmacophore structure of Tacrine (THA). Based on the principle of active substructure splicing, BMT was used as a lead compound and synthesized coumarin-BMT hybrids I [n = 5, 6, 7; R1 = H, Me, MeO, F3CO, Br; R2 = H, MeO] by introducing coumarin to BMT. In this work, 21 novel hybrids of BMT and coumarin I were synthesized and evaluated for their inhibitory activity on AChE. All obtained compounds I presented preferable inhibition. Compound I [n = 6, R1 = Me, R2 = H] was the most active compound, with the value of Ki as 49.2 nM, which was higher than Galantamine (GAL) and lower than THA. The result of mol. docking showed that the highest binding free energy was -40.43 kcal/mol for compound I [n = 6, R1 = Me, R2 = H] which was an identical trend with the calculated Ki. The results came from multiple reactions, including the reaction of m-Methoxyphenol(cas: 150-19-6Synthetic Route of C7H8O2)
