Installation of Trifluoromethylated Quaternary Carbon Stereocenters via Asymmetric Epoxidation of Tetrasubstituted Alkenes

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
The catalytic enantioselective epoxidation of acyclic tetrasubstituted alkenes, bearing a trifluoromethyl group, is reported. In the presence of Takemoto's thiourea organocatalyst and tert‐butyl hydroperoxide, epoxides are obtained with excellent yield and good to high enantioselectivity.

Cu(I)‐Catalyzed Interrupted Cycloaddition Between Azides, Ag(I)‐Acetylides, and Diorganoyl Dichalcogenides

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Unleashing the power of Ag(I)‐acetylides with LiCl/dimethyl sulfoxide (DMSO). The LiCl/DMSO mixture have an unexplored ability to dramatically increase the solubility of Ag(I)‐acetylides regardless of their molecular structure, which is explored to achieve high chemoselectivity in the Cu(I)‐catalyzed interrupted cycloaddition between organic azides, Ag(

Seamlessly Machine‐Knitted Multi‐Sensor Garment to Monitor and Quantify Dynamic Upper Body Movement

open access: yesAdvanced Sensor Research, EarlyView.
A seamlessly machine‐knitted multi‐sensor garment, that can detect multiplanar dynamic shoulder and elbow motion, is demonstrated. The garment has four strain sensors connected to a circuit board via flexible interconnects, with all components integrated into the fabric in a single manufacturing step.
