We report the silylation of primary C–H bonds located β to secondary and tertiary alcohols by exploiting perfluorinated esters as traceless directing groups. The conversion of a secondary or tertiary alcohol to a perfluoroalkyl ester and conversion of the ester to the corresponding silyl acetals ...

Regiospecific dehydration of vicinal diols by enzymes is a difficult reaction that usually requires activation by dedicated organic cofactors. The enzymatic use of radical-based chemistry is an effective but challenging alternative as radical intermediates are difficult to control. Here we report ...

19.01.2018 | Aliaksandr V. Yakutovich; Johannes Hoja; Daniele Passerone; Alexandre Tkatchenko; Carlo A. Pignedoli, Journal of the American Chemical Society, 2018
We unravel the origin of the recently observed striking enantioselectivity of the PdGa(111) surface with respect to the adsorption of a small organic molecule, 9-ethynylphenanthrene, using first-principles calculations. It turns out that the key ingredient to understand the experimental evidence ...

Most of the reported mitochondria-targeting molecules are lipophilic and cationic, and thus they may become cytotoxic with accumulation. Here we show enzymatic cleavage of branched peptides that carry negative charges for targeting mitochondria. Conjugating a well-established protein tag (i.e., ...

Photoredox catalysis has driven a revolution in the field of organic chemistry, but direct mechanistic insights into reactions of genuine synthetic utility remain relatively scarce. Herein we report ultrafast time-resolved spectroscopic observation of a bimolecular organocatalyzed photoredox ...

Because they provide lower cost but comparable activity to precious platinum (Pt)-based catalysts, nonprecious iron (Fe)-based materials, such as Fe/Fe3C and Fe–N–C, have gained considerable attention as electrocatalysts for the oxygen reduction reaction (ORR). However, their practical ...

A key material for artificial photosynthesis including water splitting is heteronanostructured (HNS) photocatalysts. The photocatalytic activity depends on the geometry and dimension, and the quality of junctions between the components. Here we present a half-cut Au(core)–CdS(shell) (HC-Au@CdS) ...

Although nanomedicines have been pursued for nearly 20 years, fundamental chemical strategies that seek to optimize both the drug and drug carrier together in a concerted effort remain uncommon yet may be powerful. In this work, two block polymers and one dimeric prodrug molecule were designed to ...
