Selective N‐Alkylation of Unprotected Amino Sugars by Alcohols. Application to the Synthesis of Sugar‐Based Surfactants

ChemistryEurope, EarlyView.
A borrowing hydrogen strategy using an NHC‐Ir(III) catalyst enables selective N‐functionalization of unprotected amino sugars using alcohols as alkylating agents. The use of unprotected substrates avoids extra steps of protection/deprotection, minimizing waste generation.

Photochemical Allylation of Aldehydes or Alkanes with Vinyl Cyclopropanes

ChemistryEurope, EarlyView.
An acylation or alkylation of vinyl cyclopropanes, employing tetra‐n‐butylammonium decatungstate as the photocatalyst, leading allyl ketones or alkenes is presented. A diverse range of substrates were compatible with this protocol, while flow conditions were also developed and mechanistic studies were also performed.

Intracellular Catalytic Photooxygenation of α‐Synuclein Amyloid

ChemistryEurope, EarlyView.
Amyloid‐selective catalytic photooxygenation reduces amyloid toxicity, aggregation tendencies, and seeding activities. Achieving therapeutic catalysis for intracellular amyloids is challenging due to conflicting oxygenation and reductive cellular environments.

Easier, Safer, and Greener: Unlocking the Power of Solid Reagents in Organic Reactions by Mechanochemistry

ChemistryEurope, EarlyView.
This review highlights the powerful synergy between mechanochemistry and solid reagents to replace hazardous substances traditionally used in organic synthesis. Such an approach offers a safer and more sustainable pathway for conducting organic reactions, with potential benefits in both reactivity and selectivity. The use of solid bases, acids, and gas
