Asymmetric synthesis of a stereopentade fragment toward latrunculins
Beilstein Journal of Organic Chemistry, 2023 Latrunculins are marine toxins used in cell biology to block actin polymerization. The development of new synthetic strategies and methods for their synthesis is thus important in order to improve, modulate or control this biological value.

Enantioselective Allylation from Allene, a Petroleum Cracking Byproduct [PDF]
, 2018 Allene (C3H4) gas is produced and separated on million-metric-ton scale per year during petroleum refining but is only rarely employed in chemical manufacturing. Meanwhile, the addition of an allyl group (C3H5) to ketone-containing molecules is among the

Iridium Catalyzed Enantioselective Intermolecular Indole C2-Allylation [PDF]
, 2020 The enantioselective intermolecular C2-allylation of 3-substituted indoles is reported for the first time. This directing group-free approach relies on a chiral Ir-(P, olefin) complex and Mg(ClO4)2 Lewis acid catalyst system to promote allylic ...

The Radical Chemistry of 2,3-Diguanidinopyridines: Coordination and Visible-Light Photochemistry. [PDF]
ChemistrySubstitution at the pyridine core of 2,3‐diguanidinopyridines was used to develop novel redox‐active molecules with three interconvertible redox states. They are applied as redox‐active ligands in coordination chemistry. Visible‐light irradiation of the pyridine N‐benzylated molecules leads to photoconversion to a higher‐energetic isomer.
