Artificial macrocycles recently became popular as a novel research field in drug discovery. As opposed to their natural twins, artificial macrocycles promise to have better control on synthesizability and control over their physicochemical properties resulting in druglike properties. Very few synthetic methods allow for the convergent, fast but diverse

Symmetric Macrocycles by a Prins Dimerization and Macrocyclization Strategy [PDF]
A tandem dimerization/macrocyclization reaction utilizing the Prins cyclization has been developed. This reaction develops molecular complexity through the formation of highly substituted dimeric tetrahydropyran macrocycles. Mild conditions utilizing rhenium(VII) catalysts were explored for aromatic substrates, while harsher Lewis acidic conditions ...

Macrocyclic Drugs and Synthetic Methodologies toward Macrocycles [PDF]
Macrocyclic scaffolds are commonly found in bioactive natural products and pharmaceutical molecules. So far, a large number of macrocyclic natural products have been isolated and synthesized. The construction of macrocycles is generally considered as a crucial and challenging step in the synthesis of macrocyclic natural products.

A ferrocene redox-active triazolium macrocycle that binds and senses chloride
A ferrocene bis(triazole) macrocycle was synthesised in good yield by the Eglinton coupling of an acyclic bis(alkyne) precursor and characterised in the solid state by X-ray crystallography. Alkylation gives the corresponding triazolium macrocycle, which

Spectral manifestation of substitution of out-of-plane ligands in metallophtalocyanines
In our study, we demonstrate the splitting effect of long-wavelength bands in absorption spectra (excitation of fluorescence) of the series of Zn(II), Ti(IV), Zr(IV) and Hf(IV) phthalocyanines at low temperatures.
