En Route Toward Sustainable Polycarbonates via Large Cyclic Carbonates

ChemSusChem, EarlyView.
The use of safe carbonylating agents, allowed by a suitable (bio)catalytic systems, affords the sustainable and green synthesis of large‐ring cyclic carbonates by reaction of renewables such as bio‐based diols. These carbonates are prone to ring‐opening polymerization paving the way for the production of circular aliphatic polycarbonates.

Phenol‐Rich Carbon Dots as Metal‐Free Nano‐Photocatalysts for [3 + 2] Cycloaddition Reactions

ChemSusChem, EarlyView.
Phenol‐rich carbon dots can be effectively used, in combination with a proper base and the Schreiner thiourea (A), as nano‐photocatalysts to drive synthetically relevant [3 + 2] cycloaddition reactions between cyclopropyl ketones 1 and unsaturated hydrocarbons 2. Carbon dots (CDs) are unique carbon‐based nanoparticles with potential applications in the

Combining photocatalytic oxidation of β‐chlorohydrins with carbonyl bioreduction in a deracemization approach

ChemSusChem, Accepted Article.
Enantiopure β‐chlorohydrins are valuable intermediates in organic synthesis, acting as chiral building blocks for obtaining biologically active compounds. This work presents a one‐pot two‐step linear sequence for the efficient deracemization of β‐chlorohydrins by combining a photocatalytic alcohol oxidation with a stereoselective carbonyl bioreduction ...

Synthesis of 19‐Hydroxyarachidonic Acid by Fungal Peroxygenases: An Experimental and Computational Study

ChemSusChem, Accepted Article.
Hydroxylated derivatives of arachidonic acid play crucial roles in physiology and inflammation response, with distinct biological effects for (R)‐ and (S)‐enantiomers, highlighting their pharmaceutical relevance. Here, we harness recombinant unspecific peroxygenases (UPOs)—from the fungi Coprinopsis cinerea (rCciUPO) and Agrocybe aegerita (rAaeUPO ...
