All‐Round Talent: Unique Zinc Guanidine Catalyst Performs Efficiently in Synthesis and Chemical Recycling of (Bio)Polyesters (Adv. Sci. 8/2026)
Graphical Abstract Unique Zinc Guanidine Catalyst The new zinc hybrid guanidine catalyst catalyzes efficiently the polymerization of cyclic esters and the chemical recycling of these polyesters. Polylactide and polycaprolactone are obtained with high molecular weights under industrially relevant bulk conditions and can be degraded either in an open-loop or a closed-loop alcoholysis process.
PCA‐Based Database Mining Enables the Discovery of Bacterial Carbene Transferases for Stereodivergent Cyclopropanation
1 Introduction With the rapid progress in biotechnology experienced in recent years, biocatalysis has emerged as a powerful synthetic tool that provides an efficient way to produce chemical feedstocks [1]. One of the main challenges associated with biocatalysis is to expand the catalytic repertoire of natural enzymes to meet the demands of synthetic chemistry.
