The title compound C16H15Br2NO4S, contains a central cyclo­hexene ring with cyclo­butane and oxazolidinone groups fused to it. All the substituents, including the oxazolidinone group and the bromine atoms, are on the same side of the fused four- and six-membered rings (syn conformation). The two bromine atoms are cis to each other.

In the title compound, C16H20Cl2O8, the bicyclic system contains a central non-planar cyclohexane ring which is fused to a cyclobutane moiety. The cyclohexane ring has a chair conformation and the whole system adopts a syn conformation. The structure provides information on the stereochemical course of the chlorination, photo-oxidation and hydroxylation steps of the reaction.

In the title compound, C31H35NO3, the central heterocyclic ring of the octahydroacridinedione system is planar while the outer two rings each adopt an envelope conformation. The buckling angle between the two halves is 8.52 (3)degrees, which shows the relative planarity of the decahydroacridinedione system. The dihedral angle between the planes of the two aromatic rings is 7.55 (7)degrees. The crystal structure is stabilized by two intermolecular C-(HO)-O-... hydrogen bonds that generate C(10) chains and an...

The structure of the title compound, C8H12O2, which is a rearrangement product of the reaction of 6-hydroxy-4,4-dimethylcyclohex-2-en-1-one and 4-dimethylaminopyridine has been identified as 2-hydroxy-5,5-dimethylcyclohex-2-en-1-one, The C atom of the six-membered ring connected to the two methyl groups is 0.617(2)Angstrom out of the least-squares plane defined by the other C atoms of the rin. The unit cell consists of discrete molecules with intra-and intermolecular hydrogen bonds.
1,5-Disubstituted 1,2,3-Triazole-Containing Peptidotriazolamers: Design Principles for a Class of Versatile Peptidomimetics
Kracker, Oliver; Gora, Jerzy; Krzciuk-Gula, Joanna; Marıon, Antoıne; Neumann, Beate; Stammler, Hans-Georg; Niess, Anke; Antes, Iris; Latajka, Rafal; Sewald, Norbert (2018-01-19)
Peptidotriazolamers are hybrid foldamers combining features of peptides and triazolamers-repetitive peptidomimetic structures with triazoles replacing peptide bonds. We report on the synthesis of a new class of peptidomimetics, containing 1,5-disubstituted 1,2,3-triazoles in an alternating fashion with amide bonds and the analysis of their conformation in solid state and solution. Homo-or heterochiral peptidotriazolamers were obtained from enantiomerically pure propargylamines with stereogenic centers in th...

The photodegradation of irradiated PETG and PCCT model compounds namely Tm-CHDM-Tm and Tm-TMCD-Tm, where Tm refers to the methyl ester of terephthalic acid, CHDM refers to 1, 4-cyclohexanedimethanol, and TMCD refers to tetramethyl-1, 3-cyclobutanediol, was analyzed using X-ray photoelectron spectroscopy. Photodegradation products were characterized based on high resolution O(1s)x-ray photoelectron spectroscopy (XPS) spectra and the spectra of irradiated model compounds showed a decrease in the relative inte...
