While the aza-[2+2] cyclization represents the most straightforward approach to azetidine synthesis, previous methodologies have been strictly limited to ketoimines, all with an EWG at the central reactive carbon, and predominantly employing cyclic imine substrates. Through rational design of an in situ-generated magnesium catalytic system and systematic investigation of imine electronic effects, we have successfully developed an asymmetric protocol for simple ketoimines. This breakthrough enables efficient access to enantioenriched monocyclic azetidines with excellent stereocontrol. Moreover, a streamlined one-pot tandem oxidation readily converts these azetidines into valuable quaternary chiral β-lactams-privileged scaffolds that are prominent in numerous pharmaceuticals and bioactive agents. A combination of comparative studies, the calculation results of the HOMO and LUMO energies of different imines, relative control experiments, and a series of detailed NLE analysis revealed the coordination difference and the catalytic cycle. The catalytic protocol was used for the synthesis of a series of β-lactams containing aryl or alkyl groups, as well as for pharmaceutical active molecules' β-lactam-modifications. Importantly, the preliminary attempt to take advantage of the significant ring strain of β-lactam for peptide modifications was also achieved on tryptophan.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"117 6 1","pages":"e202518427"},"PeriodicalIF":16.6,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145338541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we present a palladium-catalyzed regio- and enantioselective hydrophosphinylation of 2-amido and 2-alkoxyl dienes using phosphine oxides. This approach successfully constructs chiral allylic α-aminophosphine oxides and α-alkoxyphosphine oxides with tetrasubstituted carbon centers. Our method demonstrates a broad substrate scope with excellent enantioselectivity (up to > 99% ee) and high yields (up to 99%), achieving exclusive regio-control under mild conditions.

However, effective strategies to construct high-nuclearity MNCs while balancing catalytic stability and active-site exposure remain scarce. Herein, we propose a \"topological-duality-driven\" strategy to construct a high-nuclearity Cu24Ag54 nanocluster, featuring an octahedral {Cu24} shell and a double-truncated cubic {Ag54} core with exposed {Ag3} vertices on {111} facets. Notably, the double-truncated cubic is a previously unexplored concave polyhedron with over twice the number of {111} facets compared to conventional structures. As a catalyst for CO2 electroreduction, Cu24Ag54 delivers exceptional performance including a Faradaic efficiency for CO of ∼98%, catalytic stability exceeding 100 h, and current densities up to 750 mA cm-2 (total current 3 A), ranking among the highest values of the reported MNCs. Dedicated studies show the nested structure and increased electron delocalization underpin the catalyst durability. The facilitated electron transfer from Ag to the key intermediate *COOH and electron delocalization effect significantly reduce the energy barrier for *COOH formation by 50%. This work provides a new perspective on the potential of topological geometries in designing high-nuclearity MNCs for highly efficient and robust CO2 electroreduction at industrial current density.","PeriodicalId":125,"journal":{"name":"Angewandte Chemie International Edition","volume":"224 1","pages":"e202516704"},"PeriodicalIF":16.6,"publicationDate":"2025-10-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145338543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we integrate hydrogen bonding (H-B) and ring-fusion (R-F) into a diketopyrrolopyrrole (DPP)-based polymer, yielding a novel material, P-HF. For comparison, a reference polymer (P-B) and a hydrogen-bonded analogue (P-H) were synthesized. The synergistic effects of H-B and R-F dramatically not only enhance both inter- and intramolecular charge transport but also optimize the frontier orbital levels; H-B strengthens intermolecular interactions, enabling localized ordered molecular packing and tighter π-π stacking, while R-F further amplifies these effects meanwhile improving backbone planarity, extending π-conjugation, and optimizing frontier orbital levels. As a result, P-HF achieves an outstanding hole mobility of 5.02 cm2 V-1 s-1, surpassing P-B (0.71 cm2 V-1 s-1) and P-H (2.13 cm2 V-1 s-1), placing it among the highest-performing DPP-based polymers reported.

Focusing on SARS-CoV-2 viral RNA, we engineered a cleavable \"cage\" protective group into a critical site within the RIBOTAC molecule, rendering it inactive as ProRIBOTAC in its untriggered state. When therapeutic intervention becomes necessary or disease progression demands it, a bioorthogonal cleavage reaction selectively removes the protective group, activating the RIBOTAC and thus facilitating inducible degradation of SARS-CoV-2 RNA. This research not only validates the feasibility of this boRIBOTAC and the inducible SARS-CoV-2 RNA degradation strategy but also demonstrates that the boRIBOTAC approach is poised to construct a controllable and effective RNA degradation platform.

Importantly, the therapeutic potential of this approach was underscored by the treatment of cells with a TzMe complex and ICPrc-caged doxorubicin.
