Courtin, Alfred published an article in 1982, the title of the article was Syntheses of sulfonated derivatives of 4-fluoroaniline.Application In Synthesis of 5-Fluoro-2-nitrobenzene-1-sulfonyl chloride And the article contains the following content:

Thermolysis of 4-FC6H4NH2.H2SO4 gave the sulfonated derivative I (R = NH2, R1 = SO3H), the structure of which was confirmed by successive diazotization, chlorosulfonylation, hydrolysis, and Fe-HCl reduction of nitroaniline I (R = NO2, R1 = NH2). Sulfonating acetanilide II (R2 = NHAc, R3 = H) with oleum and hydrolyzing gave benzenesulfonic acid II (R2 = NH2, R3 = SO3H), the structure of which was confirmed by treating II (R2 = NO2, R3 = NH2) analogously to I (R = NO2, R1 = NH2). Sulfonating I (R = NH2, R1 = H) with oleum gave impure II (R2 = NH2, R3 = SO3H). Sulfonating I (R = NO2, R1 = H) with oleum also gave II (R2 = NO2, R3 = SO3H). The experimental process involved the reaction of 5-Fluoro-2-nitrobenzene-1-sulfonyl chloride(cas: 82711-97-5).Application In Synthesis of 5-Fluoro-2-nitrobenzene-1-sulfonyl chloride

On August 7, 2010, Zhersh, Sergey; Lukin, Oleg; Matvienko, Vitaly; Tolmachev, Andrey published an article.Related Products of 82711-97-5 The title of the article was Synthesis of isomeric fluoronitrobenzene-sulfonyl chlorides. And the article contained the following:

The synthesis of five hitherto unknown isomeric fluoronitrobenzenesulfonyl chlorides is described. The compounds are prepared from difluoronitrobenzenes by a two-step procedure. In the first step the starting compounds undergo a regioselective reaction with phenylmethanethiol giving rise to the corresponding thioethers. The oxidative cleavage of the latter with chlorine results in the sulfonyl chlorides in good yields. One example of a threefold sequential functionalization of 2-fluoro-6-nitrobenzenesulfonyl chloride showing the synthetic utility of the title compounds is provided. The experimental process involved the reaction of 5-Fluoro-2-nitrobenzene-1-sulfonyl chloride(cas: 82711-97-5).Related Products of 82711-97-5

On June 20, 2014, Abeykoon, Gayan A.; Chatterjee, Shreyosree; Chen, Jason S. published an article.Electric Literature of 35444-44-1 The title of the article was anti-Diols from α-Oxyaldehydes: Synthesis and Stereochemical Assignment of Oxylipins from Dracontium loretense. And the article contained the following:

Differentially protected 1,2-diols were synthesized by enantioselective aldehyde α-oxygenation followed by organomagnesium or -lithium addition Contrary to a previous report, the resultant diols possess an anti configuration. Good selectivity was achieved regardless of the hybridization state of the nucleophile or the presence or absence of branching. This method was applied to short syntheses of all possible stereoisomers of two oxylipins from Dracontium loretense with incomplete stereochem. assignments. Spectroscopic comparisons between the synthetic and natural oxylipins led to unambiguous assignments. The experimental process involved the reaction of Methyl 6-chloro-6-oxohexanoate(cas: 35444-44-1).Electric Literature of 35444-44-1

Qureshi, Zafar; Weinstabl, Harald; Suhartono, Marcel; Lui, Hongqiang; Thesmar, Pierre; Lautens, Mark published an article in 2014, the title of the article was Application of the Palladium-Catalyzed Norbornene-Assisted Catellani Reaction Towards the Total Synthesis of (+)-Linoxepin and Isolinoxepin.Reference of (1R,2S,5R)-2-Isopropyl-5-methylcyclohexyl carbonochloridate And the article contains the following content:

The authors’ ongoing effort towards the development of highly selective transition-metal-catalyzed carbon hydrogeb bond (C-H bond) activation processes has led to the expansion of a Catellani reaction. In a Pd0/PdII/PdIV-catalyzed tandem reaction (domino reaction), an aryl iodide, alkyl iodide and tert-Bu acrylate were combined to synthesize a carbon framework of the novel lignan (+)-linoxepin. The enantioselective synthesis highlights the work accomplished in the authors’ group and provides an excellent procedure for a reliable and scalable synthesis of architecturally complex scaffolds. This report outlines the synthetic approaches towards this interesting class of biol. active mols. After a key Catellanireaction/Heck reaction, the synthesis features a Leimeux-Johnson oxidation and a titanium tetrachloride mediated aldol condensation. Finally, a tuneable Mizoroki-Heck reaction was performed to furnish not only the natural product (+)-linoxepin but also its isoform, which we have named isolinoxepin. The synthesis of the target compounds was achieved using 8-[(5-bromo-1,3-benzodioxol-4-yl)methoxy]-3a,4-dihydro-7-(methoxy)naphtho[2,3-c]furan-1(3H)-one as a key intermediate. The title compounds thus formed included (9aR)-9a,10-dihydro-6-methoxy-4H-1,3-benzodioxolo[4,5-c]isobenzofuro[4,5,6-ef][1]benzoxepin-12(9H)-one [(+)-linoxepin] and 10,12b-dihydro-6-methoxy-4H-1,3-benzodioxolo[4,5-c]isobenzofuro[4,5,6-ef][1]benzoxepin-12(9H)-one [racemic isolinoxepin].

On August 25, 2017, Bender, Matthias; Turnbull, Ben W. H.; Ambler, Brett R.; Krische, Michael J. published an article.Electric Literature of 14602-86-9 The title of the article was Ruthenium-catalyzed insertion of adjacent diol carbon atoms into C-C bonds: Entry to type II polyketides. And the article contained the following:

Current catalytic processes involving carbon-carbon bond activation rely on π-unsaturated coupling partners. Exploiting the concept of transfer hydrogenative coupling, we report a ruthenium(0)-catalyzed cycloaddition of benzocyclobutenones that functionalizes two adjacent saturated diol carbon-hydrogen bonds. These regio- and diastereoselective processes enable convergent construction of type II polyketide substructures.

Zhou, Jiayu; Liu, Dan; Bai, Chaolumen; Bao, Agula; Muschin, Tegshi; Baiyin, Menghe; Bao, Yong-Sheng published an article in 2021, the title of the article was Transient directing group controlled regiodivergent C(sp3)-H and C(sp2)-H polyfluoroalkoxylation of aromatic aldehydes.Reference of 2-Amino-4-chlorobenzoic acid And the article contains the following content:

A novel method for achieving regiodivergent C(sp3)-H and C(sp2)-H polyfluoroalkoxylation in the o-Me benzaldehydes R-2-MeC6H3CHO (R = 3-Me, 4-MeO, 5-Br, etc.) framework by altering the transient directing group is disclosed. Using palladium as the catalyst and [F+] reagents as bystanding oxidants, various regioisomeric polyfluoroalkoxylated benzaldehydes R-6-C(CF3)2O-2-MeC6H2CHO and R-2-C(CF3)2OCH2C6H3CHO were prepared It is proposed that the selectivity is governed by the size of the palladacycle which is generated from Pd-chelation with different transient directing groups and helps in harnessing palladium with the benzyl C(sp3)-H or C(sp2)-H bonds of o-Me benzaldehydes. These findings provide an avenue for controlled regiodivergent C(sp3)-H and C(sp2)-H functionalization reactions.
