[2]Pseudorotaxane Composed of Heteroditopic Macrobicycle and Pyridine N-Oxide Based Axle: Recognition Site Dependent Axle Orientation
摘要:
A strategy for threading an axle having a hydrogen bond acceptor unit in the cavity of a C-3v symmetric amido-amine macrobicycle is investigated. The macrobicycle acts as a wheel in its neutral as well as triprotonated states to form threaded architectures with a pyridine N-oxide derivative. The negative oxygen dipole of the axle is capable of [2]pseudorotaxane formation in two different orientations with the wheel in its neutral and triprotonated states.
FGF receptor agonist compounds corresponding to the general formula: M1-L-M2 are disclosed in which M1 and M2, which may be identical or different, each represent, independently of one another, a monomer unit M, and L represents a linker group, wherein the monomer unit is of the general formula I.
