Synthesis of Pleuromutilin.
Foy NJ, Pronin SV. Foy NJ, et al. J Am Chem Soc. 2022 Jun 15;144(23):10174-10179. doi: 10.1021/jacs.2c04708. Epub 2022 Jun 2. J Am Chem Soc. 2022. PMID: 35653288 Free PMC article.
Synthesis of a potent inhibitor of bacterial protein synthesis, pleuromutilin, is described. Assembly of the critical cyclooctane fragment relies on an oxidative ring-expansion, and complete stereochemical relay in the synthetic sequence is enabled by the judicious choice …

Cyclooctane tropospheric degradation initiated by reaction with C1 atoms.
Aranda A, Díaz-De-Mera Y, Bravo I, Morales L. Aranda A, et al. Environ Sci Pollut Res Int. 2007 May;14(3):176-81. doi: 10.1065/espr2006.12.374. Environ Sci Pollut Res Int. 2007. PMID: 17561776
Nevertheless, C1 atom reaction rate constants are generally one order of magnitude larger than those of OH. In the present work, the reaction of cyclooctane with C1 atoms has been studied within the temperature range of 279-333 K. ...RECOMMENDATIONS AND PERSPECTIVES: Cl an …

3-[N,N-Bis(sulfonyl)amino]isoxazolines with Spiro-Annulated or 1,2-Annulated Cyclooctane Rings Inhibit Reproduction of Tick-Borne Encephalitis, Yellow Fever, and West Nile Viruses.
Sedenkova KN, Sazonov AS, Vasilenko DA, Andriasov KS, Eremenko MG, Grishin YK, Khvatov EV, Goryashchenko AS, Uvarova VI, Osolodkin DI, Ishmukhametov AA, Averina EB. Sedenkova KN, et al. Int J Mol Sci. 2023 Jun 28;24(13):10758. doi: 10.3390/ijms241310758. Int J Mol Sci. 2023. PMID: 37445937 Free PMC article.
In the search for novel anti-flaviviral agents, we have obtained a series of 3-[N,N-bis(sulfonyl)amino]isoxazolines containing spiro-annulated cyclooctane rings and assessed their antiviral activity against tick-borne encephalitis (TBEV), yellow fever (YFV), and West Nile …

Syntheses of Complex Terpenes from Simple Polyprenyl Precursors.
Harmange Magnani CS, Thach DQ, Haelsig KT, Maimone TJ. Harmange Magnani CS, et al. Acc Chem Res. 2020 Apr 21;53(4):949-961. doi: 10.1021/acs.accounts.0c00055. Epub 2020 Mar 23. Acc Chem Res. 2020. PMID: 32202757 Free PMC article. Review.
We then show how a radical cyclization cascade can forge the hallmark cyclooctane ring system of the complex sesterterpene 6-epi-ophiobolin N from two simple polyprenyl precursors, (-)-linalool and farnesol. ...

A whole cell biocatalyst for double oxidation of cyclooctane.
Müller CA, Weingartner AM, Dennig A, Ruff AJ, Gröger H, Schwaneberg U. Müller CA, et al. J Ind Microbiol Biotechnol. 2016 Dec;43(12):1641-1646. doi: 10.1007/s10295-016-1844-5. Epub 2016 Oct 22. J Ind Microbiol Biotechnol. 2016. PMID: 27771781
A novel whole cell cascade for double oxidation of cyclooctane to cyclooctanone was developed. The one-pot oxidation cascade requires only a minimum of reaction components: resting E. coli cells in aqueous buffered medium (=catalyst), the target substrate and oxygen as env …

Enantioselective route from carbohydrates to cyclooctane polyols.
Paquette LA, Zhang Y. Paquette LA, et al. Org Lett. 2005 Feb 3;7(3):511-3. doi: 10.1021/ol0474296. Org Lett. 2005. PMID: 15673277
[reaction: see text] A synthetic route to select cyclooctane-1,2,3-triols and 1,2,3,4,5-pentaols has been defined. The starting materials are d-glucose or d-arabinose, and the key steps consist of a zirconocene-promoted ring contraction, a [3,3] sigmatropic rearrangement, …
