The readily available and enzymatically derived cis-1,2-dihydrocatechol 3 has been converted, over 15 steps, into (+)-amabiline, the non-natural enantiomeric form of a crinine-type alkaloid.

Expanding Polycyclic Tetramate Macrolactam (PoTeM) Core Structure Diversity by Chemo-Enzymatic Synthesis and Bioengineering.
Angew Chem Int Ed Engl
December 2024
TU Dresden: Technische Universitat Dresden, Faculty of Chemistry and Food Chemistry, Bergstraße 66, 01069, Dresden, GERMANY.
Polycyclic tetramate macrolactams (PoTeMs) represent a growing class of bioactive natural products that are derived from a common tetramate polyene precursor, lysobacterene A, produced by an unusual bacterial iterative polyketide synthase (PKS) / non-ribosomal peptide synthetase (NRPS). The structural and functional diversity of PoTeMs is biosynthetically elaborated from lysobacterene A by pathway-specific cyclizing and modifying enzymes. This results in diverse core structure decoration and cyclization patterns.

Drimane-type merosesquiterpenoids (DMT) are a class of natural products with diverse structures and broad biological activity. Classical DMT synthesis relies on atom-inefficient plant-derived chiral pool building blocks, while alternative drimane-type building blocks such as drimenol and albicanol offer more direct routes but face production challenges. In this study, we engineered a microbial platform for efficient production of these building blocks.

This report describes the asymmetric synthesis of a focused library of enantiopure structured triacylglycerols (TAGs) comprised of a single saturated fatty acid (C6, C8, C10, C12, C14 or C16), a pure bioactive n-3 polyunsaturated fatty acid (EPA or DHA) and a potent drug (ibuprofen or naproxen) intended as a novel type of prodrug. One of the terminal -1 or -3 positions of the glycerol backbone is occupied with a saturated fatty, the remaining one with a PUFA, and the drug entity is present in the -2 position. This was accomplished by a six-step chemoenzymatic approach starting from enantiopure ()- and ()-solketals.

Article Synopsis
- - A new method for synthesizing resibufogenin and bufalin was developed using only seven steps without the need for protecting groups, starting from androstenedione (AD).
- - The synthesis involved introducing a hydroxyl group at C14 using hydroxylase P-450, which helped control the configuration at C17 during subsequent reactions.
- - The final steps included dehydrating the intermediate and using epoxidation to produce resibufogenin, while bufalin was synthesized through a more complex anaerobic Mukaiyama hydration process.
Activity and Biocatalytic Potential of an Indolylamide Generating Thioesterase.

The chemical synthesis of -acyl indoles is hindered by the poor nucleophilicity of indolic nitrogen, necessitating the use of strongly basic reaction conditions that encumber elaboration of highly functionalized scaffolds. Herein, we describe the total chemoenzymatic synthesis of the bulbiferamide natural products by the biochemical activity reconstitution of a nonribosomal peptide synthetase assembly line-derived (NRPS-derived) thioesterase that neatly installs the macrocyclizing indolylamide. The enzyme represents a starting point for biocatalytic access to macrocyclic indolylamide peptides and natural products.
