چکیده
The formation and high stability of the H-bond-driven supramolecular architectures of the syn and anti isomers of the dioxime of bicyclo[3.3.1]nonane-3,7-dione were investigated by single crystal X-ray diffraction, NMR, FTIR, and molecular modeling. Self-assembly of the achiral syn isomer into a cyclic trimer (supramolecular wheel) and of the chiral anti isomer into homochiral cyclic dimers was observed.

In the title compound, C(35)H(36)N(2)O(5)·0.5C(4)H(10)O, the asymmetric unit contains one bicyclo-[3.3.1]nonane mol-ecule and a half-occupancy diethyl ether solvent with the O atom lying on a crystallographic inversion center. Two intra-molecular N-H⋯O hydrogen bonds generate S(6) ring motifs. The bicyclo-[3.3.1]nonane ring system adopts a chair-boat conformation. In the crystal structure, the ...

Compounds (I), C9H10N2O4, (II), C11H12N2O4, and (III), C14H12N2O4·C3H7NO represent 9,9-disubstituted-3,7-di-aza-bicyclo-[3.3.1]nonane-2,4,6,8-tetra-one deriv-atives with very similar mol-ecular geometries for the bicyclic framework: the dihedral angle between the planes of the imide groups is 74.87 (6), 73.86 (3) and 74.83 (6)° in (I)-(III), respectively. The dimethyl derivative (I) is position...

The bicyclo-[3.3.1]nonane ring in the title compound, C(39)H(44)N(2)O, adopts a chair-boat conformation with the four benzene rings being directed away from the carbonyl group. The presence of C-H⋯O contacts leads to helical supra-molecular chains along the b axis.
متن کاملThe 3,7-diazabicyclo[3.3.1]nonane scaffold for subtype selective nicotinic acetylcholine receptor (nAChR) ligands. Part 1: the influence of different hydrogen bond acceptor systems on alkyl and (hetero)aryl substituents.
3,7-Diazabicyclo[3.3.1]nonane is a naturally occurring scaffold interacting with nicotinic acetylcholine receptors (nAChRs). When one nitrogen of the 3,7-diazabicyclo[3.3.1]nonane scaffold was implemented in a carboxamide motif displaying a hydrogen bond acceptor (HBA) functionality, compounds with higher affinities and subtype selectivity for α4β2(∗) were obtained. The nature of the HBA system...
متن کاملOne-carbon bridge stereocontrol in robinson annulations leading to bicyclo[3.3.1]nonanes.
The one-carbon bridge stereochemistry of bicyclo[3.3.1]nonane products formed in the Robinson annulation reactions of 2-substituted cyclohex-2-enones was investigated. In contrast to previous reports, it was found that the major diastereomer formed places the one-carbon bridge substituent anti to the beta-keto ester/amide unit introduced in the Robinson annulation. This stereoselectivity appear...
