Design of indole- and MCR-based macrocycles as p53-MDM2 antagonists

open access: yesBeilstein Journal of Organic Chemistry, 2019
Macrocycles were designed to antagonize the protein–protein interaction p53-MDM2 based on the three-finger pharmacophore F19W23L25. The synthesis was accomplished by a rapid, one-pot synthesis of indole-based macrocycles based on Ugi macrocyclization ...

Thiol-Yne click chemistry of acetylene-enabled macrocyclization

open access: yesNature Communications, 2022
Thiol–yne coupling is a reliable method to link two molecular units, but has not been extensively explored for the construction of macrocycles. Here, the authors use gaseous acetylene, the simplest alkyne unit, to synthesize a variety of macrocycles ...

Synthesis of new p-tert-butylcalix[4]arene-based polyammonium triazolyl amphiphiles and their binding with nucleoside phosphates

open access: yesBeilstein Journal of Organic Chemistry, 2018
The synthesis of new calix[4]arenes adopting a cone stereoisomeric form bearing two or four azide fragments on the upper rim and water-soluble triazolyl amphiphilic receptors with two or four polyammonium headgroups via copper-catalyzed azide–alkyne ...

Inner-bond-cleavage approach to figure-eight macrocycles from planar aromatic hydrocarbons [PDF]

open access: yes
Contemporary synthetic strategies in organic chemistry rely heavily on the stepwise formation of bonds between fragments of the target compound (‘bottom-up’ approach). Figure-eight aromatic macrocycles represent a considerable challenge for the bottom-up

Multicomponent Syntheses of Macrocycles

open access: yes, 2010
How to access efficiently the macrocyclic structure remained to be a challenging synthetic topic. Although many elegant approaches/reactions have been developed, construction of diverse collection of macrocycles is still elusive.

Low‐entropy‐penalty synthesis of giant macrocycles for good self‐assembly and emission enhancement

open access: yesAggregate
Macrocycles are key tools for molecular recognition and self‐assembly. However, traditionally prevalent macrocyclic compounds exhibit specific cavities with diameters usually less than 1 nm, limiting their range of applications in supramolecular ...
