Sigmatropic rearrangements - Synthesis of functionalized cyclopropanes

, 2016
Les cyclopropanes sont rencontrés dans de nombreux produits naturels ou synthétiques bioactifs. Les travaux exposés dans ce manuscrit portent sur le développement de réarrangements sigmatropiques [3,3] impliquant des dérivés de cyclopropénylcarbinols ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, Volume 600, Issue 20, Page 2981-3008, October 2026.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Rh(III)‐Catalyzed Cascade C─H Activation/[4 + 1] Annulation: A Direct Route to Benzofuran‐‍Fused Succinimides From Aromatic Acids and 3‐Methylmaleimides

Advanced Synthesis &Catalysis, Volume 368, Issue 19, 1 October 2026.
Benzofuran‐linked succinimides have been developed from aromatic carbocyclic and heterocyclic acids, as well as 3‐methylmaleimides, using a Rh(III)‐catalyzed C─H activation and [4+1] annulation cascade reaction. A Rh(III)‐catalyzed [4 + 1] cyclization of aromatic carbocyclic/heterocyclic acids with 3‐methylmaleimides has been developed, providing an ...

Palladium‐Photocatalyzed C3‐Alkylation of Coumarins With Alkyl Bromides: Development and Mechanistic Insights

Advanced Synthesis &Catalysis, Volume 368, Issue 19, 1 October 2026.
Visible‐light palladium catalysis enables the direct C3‐alkylation of coumarins with readily available alkyl bromides under mild conditions. Mechanistic studies support radical addition followed by base‐assisted deprotonation and outer‐sphere electron transfer, allowing product formation and catalyst regeneration without formation of a PdC bond.
