CuAAC Macrocyclization: High Intramolecular Selectivity through the Use of Copper–Tris(triazole) Ligand Complexes
摘要:
A range of multivalent heteroaryl ligands, copper sources, and solvent systems have been Investigated for use in CuAAC-mediated macrocyclization reactions. These studies have revealed the key factors governing selectivity for macrocyclization versus dimerization and identified a simple but specific set of reaction conditions capable of efficiently generating a diverse series of drug-like macrocycles at modest dilution in up to 95% yield.

A series of novel 13- to 15-member hydroxyproline-based macrocycles, which contain alkyl-alkyl ether and alkyl-aryl ether moieties, have been synthesized by the strategy of macrocyclization utilising azide-alkyne cycloaddition, Mitsunobu protocol and amide formation. Their anti-tumor activities towards A549, MDA-MB-231 and Hep G2 cells were screened in vitro by an MTT assay. The results indicated that
