Acetylation‐Deacetylation‐Driven Natural Product Biosynthesis

ChemistryEurope, EarlyView.
This review summarizes the role of acetylation‐deacetylation in natural product biosynthesis, including acetylation followed by deacetylation after several biosynthetic steps, acetylation‐mediated rearrangement, acetylation‐triggered elimination, and the acetylation cycle as a regulatory mechanism. These processes are vital for the formation of complex

Identification of Pyrrolizilactone Biosynthetic Gene Cluster with Unique Short‐Chain Dehydrogenase Gene for 3‐Methylproline Formation

ChemistryEurope, EarlyView.
A standalone enzyme, derived from the reductase domain of a polyketide synthase‐nonribosomal peptide synthetase hybrid enzyme, is identified as a pyrroline carboxylate reductase. This enzyme is involved in the biosynthesis of 3‐methylproline, an amino acid building block of a unique tricyclic pyrrolizidinone structure of a fungal metabolite ...

Catalytic Oxidation of Naphthalene and Polycyclic Arenes by Iron(III) TAML/H2O2 in Water Aiming at Their Efficient Removal from Aqua Natural Systems

Chemistry – A European Journal, EarlyView.
Fe‐TAML in the presence of hydrogen peroxide efficiently catalyzes the oxidative degradation of naphthalene in aqueous medium of neutral pH. Products are identified and key mechanistic features are discussed. Abstract The electron transfer from naphthalene at an oxidized iron TAML species (TAML = tetraamido macrocyclic ligand) is a key step of its ...
