Harnessing nanomaterials to precisely regulate the immunosuppressive tumor microenvironment for enhanced immunotherapy

BMEMat, EarlyView.
The immunosuppressive tumor microenvironment, characterized by hypoxia, redox imbalance, elevated interstitial fluid pressure, and acidity, was comprehensively elucidated. This review discussed the etiology and consequences of the characteristics of the immunosuppressive tumor microenvironment, and analyzed the recent advancements in nanomaterials for ...

Synthesis of α‐Pentafluorosulfanylated‐β2,3‐Amino Esters

ChemistryEurope, EarlyView.
De novo α‐SF5‐β2,3‐amino esters are now accessible through a straightforward aza‐Michael reaction using a series of newly developed (E)‐α‐SF5‐α,β‐unsaturated esters. Two new, highly functionalized, contiguous tertiary stereocenters are formed with diastereodivergence governed by the choice of solvent and/or base.

Photoinduced Boron‐Catalyzed Direct α‐Aminoxylation of Carboxylic Acids

ChemistryEurope, EarlyView.
A boron‐catalyzed α‐aminoxylation of carboxylic acids enables rapid access to sterically congested α‐(aminoxy)carboxylic acids. Photoexcited diboron enediolates transfer energy to O‐sulfonylhydroxylamines, triggering SO bond cleavage to generate N‐oxyl radicals.

Synthesis of Oligo‐Sulfonimidates by Exponential Growth via Sulfur‐Phenolate Exchange Reactions

ChemistryEurope, EarlyView.
A highly flexible iterative exponential growth strategy is used in combination with the sulfur‐phenolate exchange reaction to develop sequence‐defined oligosulfonimidates (16 mer). Combining this with sulfur‐fluorine exchange‐based iterative step growth, a bespoke 20 mer (Mw = 8.5 kDa) can be synthesized.
