Concerted C–N/C–H Bond Formation in Highly Enantioselective Yttrium(III)-Catalyzed Hydroamination [PDF]
, 2011 A highly active oxazolinylborato yttrium hydroamination catalyst provides 2-methyl-pyrrolidines with excellent optical purities. The proposed mechanism, in which a yttrium(amidoalkene)amine complex reacts by concerted C–N and C–H bond formation, is ...

Advanced Functional Materials, EarlyView.Synthetic cells are engineered herein to respond to an external chemical messenger by the activation of intracellular catalysis. The chemical messenger molecules are catalytically generated by an extracellular enzyme or a mineral surface, whereas the intracellular catalysis emerges via direct enzyme activation or via protein refolding.

Design and synthesis of pyrrolidine-based nucleotide mimetics for use as inhibitors of the DNA repair enzyme AAG. [PDF]
, 2018 The action of the DNA repair enzyme alkyladenine DNA glycosylase (AAG), as part of the Base Excision Repair pathway, on alkylation-induced DNA damage has been shown in mice to lead to cell death in the retina, spleen, thymus and cerebellum. The action of

Chemistry – A European Journal, Volume 28, Issue 67, December 1, 2022., 2022 The chemical evolution of polyketide natural products leads to the unprecedented combination of biosynthetically related fragments in arrangements not found in Nature. The pseudo‐natural product grismonone was identified to be a potent inhibitor of Hedgehog signaling – a bioactivity that is not shared by its guiding fragments.

Synthesis of 1,2-diaminotruxinic d-cyclobutanes by BF3-controlled [2 + 2]-photocycloaddition of 5(4H)-oxazolones and stereoselective expansion of d-cyclobutanes to give highly substituted pyrrolidine-2,5-dicarboxylates [PDF]
, 2023 The irradiation of (Z)-4-arylidene-5(4H)-oxazolones 1a–1u with blue light (465 nm) in the presence of the photosensitizer [Ru(bpy)3](BF4)2 (2.5 mol%) and the Lewis acid BF3·OEt2 (2 equiv.) in deoxygenated methanol at room temperature affords the ...

Recent Advances in Wide‐Bandgap Perovskite Solar Cells
Advanced Materials, EarlyView.Ubiquitous defects predominately account for photo‐instability and open‐circuit voltage losses in wide‐bandgap perovskite solar cells (WBG PSCs). This review comprehensively presents the underlying impact mechanisms, summarizes the advanced optimization strategies across various functional layers and their interfaces to develop efficient and stable WBG
