Atroposelective Construction of Axially Chiral Tetraarylethenes Via NHC‐Catalyzed Desymmetrization
Advanced Science, EarlyView.We report the first NHC‐catalyzed atroposelective synthesis of axially chiral TAEs via oxidative desymmetrization of prochiral TAE dialdehydes. This catalytic strategy operates under mild conditions and accommodates a broad range of phenolic and nitrogen nucleophiles, delivering diverse axially chiral TAEs in good yields and up to 99% ee.

Chlorosulfination With Thionyl Chloride of Aromatic Methyl Ethers Containing Other Functional Groups
, 1992 Further studies on the direct chlorosulfination with thionyl chloride of aromatic methyl ethers are described. In some cases (e.g. 1,6-dimethoxynaphthalene, 1,2,4 trimethoxybenzene, ethyl 3,5- and 3,7-dimethoxy-2-naphthoate, 3,5-dimethoxyphenyl benzoate)

Advanced Science, EarlyView.The weakly‐solvating TFMSPyr electrolyte tailors the Li+ solvation structure by suppressing solvent coordination and promoting anion‐dominated solvation. This unique solvation environment induces preferential anion decomposition at electrode interfaces, forming robust inorganic rich S/CEI.

Gold-Catalyzed Rearrangement of (Silylcyclopropenyl)methyl Ethers into (Silylmethylene)cyclopropanes
, 2016 International audienceMethoxymethyl ethers derived from 2-(dimethylphenylsilyl)cycloprop-1-enyl carbinols undergo gold-catalyzed rearrangement leading to [(Z)-(dimethylphenylsilyl)methylene]cyclopropanes in moderate to high yields with methyl formate as ...

Mechanism‐Informed Machine Learning Enables Discovery of Oncolytic Peptides for Cancer Immunotherapy
Advanced Science, EarlyView.MISPOP integrates ensemble learning with membrane‐active physicochemical priors to identify Dermaseptin‐S9, a natural oncolytic peptide that disrupts tumor membranes, triggers immunogenic cell death, and shows strong antitumor activity. The study illustrates a mechanism‐informed route from peptide sequence data to cancer immunotherapy leads.

Mass spectra of steroidal alkyl ethers-I
, 1972 The mass spectral fragmentation of saturated and unsaturated steroidal methyl and ethyl ethers and ethers of 4,4-dimethyl steroids are studied and compared to the fragmentation of steroidal alcohols, trimethylsilyl ethers and ethylene ketals.

Photocatalytic Synthesis of Pentafluorosulfanyl Ketones, Acetals, and BCP Motifs Utilizing SF6
Advanced Science, EarlyView.A photocatalytic single electron reduction strategy is reported for the activation and valorization of sulfur hexafluoride (SF6), a potent greenhouse gas. Under mild conditions, SF6 is reduced to generate pentafluorosulfanyl (SF5) radicals, enabling direct access to pentafluorosulfanyl ketones, acetals, and BCP motifs.
