Beshanzoides A-D, unprecedented cycloheptanone-containing polyketides from Penicillium commune P-4-1, an endophytic fungus of the endangered conifer Abies beshanzuensis.
Chen HW, Jiang CX, Li J, Li N, Zang Y, Wu XY, Chen WX, Xiong J, Li J, Hu JF. Chen HW, et al. RSC Adv. 2021 Dec 14;11(63):39781-39789. doi: 10.1039/d1ra08377e. eCollection 2021 Dec 13. RSC Adv. 2021. PMID: 35494150 Free PMC article.
A number of previously undescribed (1-7) and structurally related known (8-17) isobenzofuran-type polyketides were obtained from the fermentation of Penicillium commune P-4-1, an endophytic fungus isolated from the fresh trunk bark of the critically endangered conifer Abies besha …

Cascade Synthesis of 3-Functionalized Indoles from Nitrones and Their Conversion to Cycloheptanone-Fused Indoles.
Kroc MA, Prajapati A, Wink DJ, Anderson LL. Kroc MA, et al. J Org Chem. 2018 Feb 2;83(3):1085-1094. doi: 10.1021/acs.joc.7b02638. Epub 2017 Nov 27. J Org Chem. 2018. PMID: 29160697
The heterocycles prepared through the hydrogen bond donor catalyzed cascade reaction are poised to undergo a McMurry coupling to form previously synthetically elusive cycloheptanone-fused indoles. The scope of these transformations is discussed as well as mechanistic exper …

Enantioselective deprotonation of meso-cycloheptanone derivative: application to the synthesis of a potential intermediate for pseudomonic acid B.
Honda T, Kimura N. Honda T, et al. Org Lett. 2002 Dec 12;4(25):4567-70. doi: 10.1021/ol027192i. Org Lett. 2002. PMID: 12465939
[reaction: see text] A novel synthetic path to a potential intermediate for the synthesis of pseudomonic acid B was established by employing enantioselective deprotonation of a meso-cycloheptanone derivative bearing hydroxy groups at the 3,4,5,6-positions with lithium (S,S …

1,2,4,5-Tetrakis(phenylsulfonyl)benzene: a novel quadruped host with D2 symmetry having ordered sulfolane and cycloheptanone guests.
Farrugia LJ, Gall JH, MacNicol DD. Farrugia LJ, et al. Chem Commun (Camb). 2012 Nov 7;48(86):10600-2. doi: 10.1039/c2cc35647c. Chem Commun (Camb). 2012. PMID: 22936121
The title tetrasulfone 1, in common with higher members of the multi-armed aromatic hosts, forms host-guest complexes with polar guest molecules. In the sulfolane and cycloheptanone complexes the host molecule possesses an abab conformation with exact C(2,) and approximate …

(2E,7E)-2,7-Bis[(thio-phen-2-yl)methyl-idene]cyclo-hepta-none.
Nithya C, Sithambaresan M, Prathapan S, Kurup MR. Nithya C, et al. Acta Crystallogr Sect E Struct Rep Online. 2014 May 31;70(Pt 6):o722. doi: 10.1107/S1600536814011866. eCollection 2014 Jun 1. Acta Crystallogr Sect E Struct Rep Online. 2014. PMID: 24940291 Free PMC article.
The whole molecule of the title compound, C17H16OS2, is generated by two-fold rotational symmetry. The carbonyl C and O atoms of the cycloheptanone ring lie on the twofold rotation axis which bisects the opposite -CH2-CH2- bond of the ring. ...

Synthesis, Morphology, and Crystallization Kinetics of Polyheptalactone (PHL).
Caputo MR, Olmos A, Li B, Olmedo-Martínez JL, Malafronte A, De Rosa C, Sardon H, O'Reilly RK, Dove AP, Müller AJ. Caputo MR, et al. Biomacromolecules. 2023 Jul 10;24(7):3256-3267. doi: 10.1021/acs.biomac.3c00305. Epub 2023 Jun 21. Biomacromolecules. 2023. PMID: 37343113 Free PMC article.
First, we synthesized the eta-heptalactone monomer by the Baeyer-Villiger oxidation of cycloheptanone before several polyheptalactones of different molecular weights (in the range between 2 and 12 kDa), and low dispersities were prepared by ring-opening polymerization (ROP …
