A Wagner–Meerwein‐Like Rearrangement Generates a Vinyl Group in the Biosynthesis of the Polychlorinated Lipopeptides Fischerazoles

Angewandte Chemie, EarlyView.
The fischerazoles, unusual cyanobacterial chlorinated lipopeptides are reported. During their biosynthesis, a linear fatty acyl‐acyl carrier protein (ACP) precursor is rearranged through the action of the S‐adenosyl‐methionine (SAM)‐dependent methyltransferase FshF, to generate a pendant vinyl group.

Synthesis, molecular modeling and bioactivity of new bis-thiazole, thiazole-pyrazole, and thiazole-pyridine analogues

Journal of Saudi Chemical Society, 2023
Several new thiazole derivatives linked pyrazole and/or pyridine rings were synthesized based on the versatile precursor 2-(5-acetyl-4-methyl-3-phenylthiazol-2(3H)-ylidene)acetonitrile (1). The synthesized derivatives were optimized using DFT approach in order to inspect the configurations and energies of the HOMO-LUMO orbitals.

Borylcyclopropanes: Synthetic Strategies and Applications

Angewandte Chemie, EarlyView.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...

Remapping the Synthetic Landscape of α‐Tertiary Alkylamines via Dual‐Functional Catechol

Angewandte Chemie, EarlyView.
A three‐component assembly strategy has been developed for the modular synthesis of hindered α‐tertiary aliphatic amines from readily available precursors through unlocking the dual role of catechol. The practicality of this methodology has been demonstrated in over 90 examples, including compounds that are otherwise difficult to access, along with ...

Azole γ‐Peptides Helix Switching via Heterocycle Substitutions

Angewandte Chemie, EarlyView.
Heterocycle substitution in azole‐based γ‐amino acids enables control over the helical shape of heterocyclic γ‐peptides. S↔N permutation in thiazole residues switches a canonical 9‐helix into a flexible helix exhibiting discontinuous hydrogen bonding.

Biosynthesis of the Thiamin-Thiazole in Eukaryotes: Identification of a Thiazole Tautomer Intermediate [PDF]

Journal of the American Chemical Society, 2008
Thiamin thiazole biosynthesis in eukaryotes is still not completely understood. In this report, a late intermediate, tightly bound to the active site of the Saccharomyces cerevisiae thiazole synthase, was identified as an adenylated thiazole tautomer. The reactivity of this unusual compound was evaluated.
