Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Enantioselective Addition of Nitrones to Activated Cyclopropanes

, 2016
In this paper, we demonstrate the first examples of chiral Lewis acid catalysis in the formation of tetrahydro-1,2-oxazines with very high enantioselectivity starting with diactivated cyclopropanes and nitrones (>90% yields and ee).

Metal‐Catalyzed Benzannulation: Recent Advances in Catalyst Design, Mechanistic Insights, and Aromatic Framework Construction

The Chemical Record, EarlyView.
This review offers a contemporary overview of metal‐catalyzed benzannulation (2018–present) encompassing transition, main‐group, post‐transition, and rare‐earth‐metal catalysts. It systematically highlights catalyst design, mechanistic insights, stereo‐ and regioselectivity, and synthetic applications toward aromatic and heteroaromatic scaffolds, while

Chemo-, regio- and enantioselective hydroformylation of trisubstituted cyclopropenes: access to chiral quaternary cyclopropanes

Nature Communications
Catalytic asymmetric synthesis of polysubstituted chiral cyclopropane presents a significant challenge in organic synthesis due to the difficulty in enantioselective control.

Enantioselective Synthesis of Trifluoromethyl-Substituted Cyclopropanes

, 2016
The reaction of 1-aryl-2,2,2-trifluorodiazoethanes with alkenes, catalyzed by the adamantylglycine-derived dirhodium complex Rh2(R-PTAD)4, generates trifluoromethyl-substituted cyclopropanes with high diastereoselectivity (>94%) and enantioselectivity ...

Cytoplasmic Lipid Membrane Biogenesis in Prokaryotes: From Soluble Lipid Building Blocks to a Dynamic and Functional Boundary Layer

ChemBioChem, Volume 27, Issue 20, 28 October 2026.
Lipid membranes are fundamental to all prokaryotic life. Besides acting as barrier, by orienting as hydrophobic bilayer, lipids are involved in a wide variety of other cellular processes. As a consequence, prokaryotic membranes are dynamic entities that switch their lipid composition as required; a process that requires tight interplay with the lipid ...

Modular and Stereoselective Synthesis of Cyclobutane β‐Amino Alcohols

Angewandte Chemie, Volume 138, Issue 43, 19 October 2026.
Late‐stage functionalization and photoisomerization of 1,2‐azaborine leads to a general strategy for the synthesis of diversely substituted cyclobutane β‐amino alcohols. The relative stereochemistry of the resulting products is unambiguously defined by the stereospecific and stereoselective nature of the photoisomerization‐hydrogenation‐oxidation ...

Observation of unusual outer-sphere mechanism using simple alkenes as nucleophiles in allylation chemistry

Nature Communications
Transition-metal catalyzed allylic substitution reactions of alkenes are among the most efficient methods for synthesizing diene compounds, driven by the inherent preference for an inner-sphere mechanism.
