The synthesis of a pyridine-N-oxide isophthalamide rotaxane utilizing supplementary amide hydrogen bond interactions.
نویسندگان
چکیده
The synthesis of a pyridine-N-oxide containing rotaxane, not requiring an additional ionic template, has been achieved in 32% yield. Successful rotaxane formation is dependent upon the structure of the isophthalamide macrocycle used, an observation which has been rationalised by a combination of NMR spectroscopy, X-ray crystallography and computational modelling.

Self-assembly of [2]rotaxane exploiting reversible Pt(II)- pyridine coordinate bonds.
A dinuclear self-assembled cationic macrocycle based on Pt(II)-N(pyridine) coordinative bonds and having competitive triflate anions, as metal counterions, is used in the construction of [2]rotaxane and [2]pseudorotaxane architectures assisted by hydrogen bonding. The kinetic lability of the Pt(II)-N(pyridine) coordinative bond controls the dynamics of the [2]rotaxane.
متن کاملBinding of group 15 and group 16 oxides by a concave host containing an isophthalamide unit
A bi-macrocycle with an incorporated isophthalamide substructure was synthesized by double amide formation between an isophthaloyl dichloride and two equivalents of a bis(alkenyloxy)aniline, followed by ring-closing metathesis and hydrogenation. In contrast to many related isophthalamides, the concave host exhibits a better binding for oxides, such as DMSO or pyridine-N-oxide, than for halide a...
متن کاملBimodal dynamics of mechanically constrained hydrogen bonds revealed by vibrational photon echoes.
We have investigated the dynamics of the hydrogen bonds that connect the components of a [2]rotaxane in solution. In this rotaxane, the amide groups in the benzylic-amide macrocycle and the succinamide thread are connected by four equivalent N-H⋅⋅⋅O=C hydrogen bonds. The fluctuations of these hydrogen bonds are mirrored by the frequency fluctuations of the NH-stretch modes, which are probed by ...
متن کاملSodium and barium cation-templated synthesis and cation-induced molecular pirouetting of a pyridine N-oxide containing [2]rotaxane.
Sodium and barium metal cation templation has been used to construct a novel pyridine N-oxide containing [2]rotaxane. Upon addition and removal of metal cations, the macrocyclic component is observed to undergo a pirouetting motion around the pyridine N-oxide axle.
