Stereo- and Regiocontrolled Methylboration of Terminal Alkynes Open
[Image: see text] A scalable and operationally simple synthesis of trisubstituted alkenyl boronic esters has been achieved using a Zr-catalyzed carboalumination of terminal alkynes followed by in situ transmetalation with i-PrOBpin. The pr…

Enantiodivergent Synthesis of Allenes by Point‐to‐Axial Chirality Transfer Open
An enantiodivergent method for the synthesis of multiply substituted allenes is described. Highly enantioenriched, point‐chiral boronic esters were synthesized by homologation of α‐seleno alkenyl boronic esters with lithiated carbamates an…

Catalyst-Free Insertion of Sulfoxonium Ylides into Aryl Thiols. A Direct Preparation of β-Keto Thioethers Open
Insertion of sulfoxonium ylides into the S-H bond of aryl thiols without the need for a catalyst is demonstrated, furnishing β-keto thioethers in excellent yield in most cases. The method overcomes traditional syntheses that employ metal c…
