Chemists use light energy to produce small molecular rings
In the search for new active agents in medicine, molecules whose atoms are linked in rings are becoming increasingly important. Such ring systems have particularly suitable properties for producing such active agents and they are driving the development of innovative treatments for malignant tumours, as well as for neurodegenerative and infectious diseases. A team of chemists headed by Prof. Frank Glorius from the University of Münster has now succeeded in synthesising new and medically significant small molecular rings, which are difficult to produce because they are particularly sensitive. The team's work has been published in the journal "Nature Catalysis". Among chemists, especially the synthesis of small ring systems from so-called aromatic compounds is considered to be difficult. Also, an especially large amount of energy is needed for the process. A further hurdle is that the energy has to be released selectively to the source materials, but not to the heat-sensitive products.
