In this study an efficient and direct production procedure for a macrocyclic polyether N,N′-diallyl-7,16-diaza-1,4,10,13-tetraoxa-dibenzo-18-crown-6 from the reaction of catechol and N,N-bis(2-chloroethyl)prop-2-en-1-amine in n-butanol in the presenc...
Macrocycles represent an important class of compounds that are widespread in nature. Of particular interest to researchers are aromatic macrocyclic compounds, which, due to their rigid structure and unique physicochemical properties, can find applica...
Cyclic organic compounds with several ether linkages in their structure are of much concern in our daily life applications. Crown ethers (CEs) are generally heterocyclic and extremely versatile compounds exhibiting higher binding affinity. In recent...
A macrocyclic receptor based on azopyrrole and polyether was synthesized, and its structure was characterized by NMR (1H and 13C), HRMS and X-ray crystallography. In the solid state, the macrocyclic molecules could bind methanol through a pair of N-H...
Based on (5Z,9Z)-tetradeca-5,9-diene-1,14-dioic acid, previously undescribed polyether aromatic macrodiolides were synthesized in good yields (53–67%). The cytotoxicity of the resulting macrocyclic compounds in vitro against tumor Jurkat cells,...
Halichondrin B is a complex, natural, polyether macrolide derived from marine sponges. Eribulin is a structurally-simplified, synthetic, macrocyclic ketone analogue of Halichondrin B. Eribulin was approved by United States Food and Drug Administratio...
Entropy-Driven Ring-Opening Polymerisation represents an attractive mechanism to produce high-performance polymeric materials as it can be performed using neat, low-viscosity precursors and without the production of by-products or release of volatile...
Lariat ethers are macrocyclic polyethers—crown ethers—to which sidearms are appended. 4,13-Diaza-18-crown-6 having twin alkyl chains at the nitrogens show biological activity. They exhibit antibiotic activity, but when co-administered at...
