Revolutionary “Clip-Off” Strategy for Macrocycles from Covalent Organic Frameworks [PDF]

open access: yesResearch
The synthesis of complex organic macrocycles, particularly large and rigid variants, has long been hampered by low yields, poor selectivity, and arduous purification stemming from stepwise approaches. Sánchez-Naya et al.

Synthesis of N-doped chiral macrocycles by regioselective palladium-catalyzed arylation [PDF]

open access: yesBeilstein Journal of Organic Chemistry
A series of nitrogen (N)-doped macrocycles was successfully synthesized through palladium-catalyzed arylation. X-ray crystallographic characterization revealed the formation of isomeric products depending on the substituents on the N atoms.

Macrocycles in Drug Discovery [PDF]

open access: yes, 2019
Macrocycles are a ring architecture of 12 or more atoms that allows them to highly dynamically adapt to large receptor surfaces, e.g. in protein–protein interactions (PPIs).

Supramolecular Macrocyclic Iodine Adsorbents Enable Photothermally Stable Perovskite Solar Cells [PDF]

open access: yesAdvanced Science
In this study, the design and synthesis of two novel diazapentacene‐based macrocycles (M3 and M4) is reported via a one‐pot Yamamoto coupling reaction. These macrocycles are constructed by π‐extension of a dihydrophenazine core, maintaining its excellent

Assembly and Disassembly of Supramolecular Hypervalent Iodine Macrocycles via Anion Coordination [PDF]

open access: yes, 2023
This study explores the dynamic self-assembly of hypervalent iodine-based macrocycles (HIMs) driven by secondary bonding interactions. The reversible disassembly and reassembly of HIMs are facilitated through anion binding via addition of ...
