Remapping the Synthetic Landscape of α‐Tertiary Alkylamines via Dual‐Functional Catechol
Angewandte Chemie, EarlyView.A three‐component assembly strategy has been developed for the modular synthesis of hindered α‐tertiary aliphatic amines from readily available precursors through unlocking the dual role of catechol. The practicality of this methodology has been demonstrated in over 90 examples, including compounds that are otherwise difficult to access, along with ...

Two‐Way Shape Memory Polymer Composite Gripper for Adaptive Robotic Applications
Advanced Materials Technologies, EarlyView.A two‐way shape memory polymer (SMP) composite is developed with intrinsic shape‐changing capability driven solely by temperature, eliminating external actuation loads. Embedding the SMP in a low‐stiffness elastomeric matrix enabled reversible transformations during heating and cooling cycles.
