Candida antarctica lipase B catalysed concurrently with the intermolecular ring-opening polymerisation, and also the formation of macrocycles by an intramolecular condensation reaction.
Reversible linear arrays of a prepore-trapped mutant form of perfringolysin have demonstrated that CDCs undergo transient, yet specific, intermolecular interactions that precede ring closure (Hotze et al., 2012).
This result has been rationalized on the basis of different intermolecular interactions between phenyl rings, occurring for trans-planar and helical s-PS crystalline phases.
Reaction of AgNO3 with Hima afforded a neutral one-dimensional (1-D) chains [Ag ima)]n (1) which exhibits a pseudo two-dimensional (2-D) layered architecture through π π stacking interaction between imidazole rings and intermolecular Ag⋯Ag interactions.
Here, we have shown a model for plausible intermolecular interactions where the benzene ring of the benzyl groups shows π-π stacking interaction with the benzene ring of the benzyl group of another dipeptide.
In the crystal structure, a self-assembling two-dimensional (2-D) layer supramolecular architecture is formed through intermolecular hydrogen bonds, CO···π (thiadiazole ring) and π···π stacking interactions.
While for the intramolecular variants described above, the classic reaction pathway is less favorable than the redox pathway (four-membered vs six-membered ring formation), any intermolecular redox transformation would necessarily have to compete with its classic counterpart.
Tb · L is a mononuclear complex with a 46-membered macrocyclic rings constructed by intermolecular hydrogen bond.
