Chemoenzymatic Route toward a De Novo Enantioselective Total Synthesis of (S)‐Baclofen Based on Metal‐Catalyzed Hydroformylation and Enzymatic Transamination

ChemBioChem, EarlyView.
A unique chemoenzymatic synthesis route toward (S)‐baclofen is presented, which highlights a hydroformylation and biocatalysis step toward the synthesis of such a challenging β‐chiral amino acid. The shown methodology exhibits high conversions and enantiomeric excess and is transferable to other β‐chiral amines and amino acids.

Diastereoselective, Diversifiable Synthesis and Biological Evaluation of the Virginiamycin Inducers, the Virginiae Butanolides

ChemBioChem, EarlyView.
Production of natural products is tightly regulated, resulting in many silent biosynthetic gene clusters. BarA is a repressor that downregulates production of the virginiamycin antibiotics. The VBs are ligands for BarA that reverse its repression of virginiamycin production.

From Biomass to Polymers: Kinetic Analysis and Sustainable Synthesis of Lignin‐Polycaprolactone Copolymers

ChemCatChem, EarlyView.
Lignin‐polycaprolactone (PCL) copolymers were prepared using a highly efficient and nontoxic zinc catalyst. The reaction kinetics were investigated and differ from those usually observed in ring‐opening polymerization. Depending on the chain length of the copolymer, an acceleration of the reaction was found.
