Bioinspired Design and Synthesis of Polyphenolic Star‐Like and Hyperbranched Polyester Models
Chemistry – A European Journal, EarlyView.Gallotannin‐inspired star‐like and hyperbranched aromatic polyesters were synthesized from D‐glucose and ABn‐type phenolic acid monomers, such as protocatechuic acid. This bioinspired approach afforded polyphenolic polymeric nanoparticles able to encapsulate hydrophobic dyes, opening new perspectives for biobased encapsulation and delivery systems ...

Photosensitizing Au(I) Catalysis With Coumarins
Chemistry – A European Journal, EarlyView.A Au(I) complex with a tethered coumarin fragment was synthesized and characterized by UV‐vis and emission spectroscopy. Its ability to facilitate photo‐driven cross‐coupling reactions through single‐electron and energy transfer events was evaluated. ABSTRACT Gold catalysis shows versatility in a wide range of challenging transformations, wherein light‐

Synthesis of Pyridinium Moiety Containing Triazolyl Purines
MolbankPyridinium salts of 2-piperidinyl-6-triazolylpurine derivatives were obtained by the introduction of pyridinium moieties into the propane-1,3-diol fragment at the N(9) position of purine to enhance the solubility of 2-amino-6-triazolylpurine derivatives ...

FLP Mediated Conversion of Difluorobenzylalkynes to Fluoroallenyl Oniums via an SN1’ Pathway
Chemistry – A European Journal, EarlyView.Frustrated Lewis pair (FLP) selective C‒F activation of difluorobenzylalkynes allows the formation of fluoroallenic oniums via an SN1’ substitution pathway. The fluoroallenic onium salts are synthetic precursors that allow subsequent functionalization at allenic and onium positions.
