Enantioenriched Alkylboron Synthesis Via a Chiral Diborylalkane Platform

Developing new reagents is one efficient strategy for expanding accessible chemical space. Recently, gem-diborylalkanes have emerged as a versatile class of boron-containing reagents with broad reactivity. However, most gem-diborylalkanes are achiral due to the pair of identical boryl groups, which restricts their util...

Visible Light-Mediated Decarboxylative Annulations of Oxamic Acids and Alkynes via Hydrogen Atom Transfer

β- and γ-lactams are critically important heterocycles in organic and medicinal chemistry, primarily due to their potent biological activities and distinctive three-dimensional architectures. Herein, a facile photochemical synthesis of a range of functionalized β- and γ-lactams derivatives from decarboxylative annula...

Enantioselective Decarboxylative Synthesis of Chiral α-Silylamines and α-Germylamines

Metalloids bridge the properties of metals and nonmetals, creating unique opportunities in drug discovery. However, the potential of silicon- and germanium-containing scaffolds in organic synthesis and medicinal chemistry remain underexplored, largely owing to the lack of general stereocontrolled synthetic methods, p...

Regiospecific α-arylation of diverse carbonyl compounds using an organobismuth transporter

The α-arylation of carbonyl compounds is a cornerstone transformation in the synthesis of pharmaceuticals and natural products. Despite decades of effort using transition metal, main-group, and photoredox strategies, a general and practical α-arylation method with broad substrate scope has remained elusive. Here we sho...

Bromonium-catalyzed 1,2-diamination of various conjugated alkenes

Alkene functionalization via cyclic halonium intermediates is highly effective for stereocontrol, and a catalytic approach further expands this strategy, offering access to more advanced functionalization. Although various studies have utilized halonium species, expanding their scope to electron-deficient or π-conjugat...

Catalytic Enantioselective Aziridination of Z-Disubstituted Alkenes with Aspartyl β-Turn-Based Dirhodium(II) Metallopeptides and Assessment of Catalyst Scaffold Versatility

We report an enantioselective aziridination of open-chain Z-disubstituted alkenes, enabled by a dirhodium(II) metallopeptide featuring finely tuned, β-turn-biased peptidyl ligands. This method affords cis-aziridines in up to 99:1 er and exhibits broad tolerance toward diverse aryl substitution patterns and peripheral f...
