Dual‐Functional Ingestible Passive Capsules for High‐Throughput Intestinal Sampling with Sealed Containment and Targeted Drug Delivery

open access: yesAdvanced Robotics Research, EarlyView.
To address challenges in high‐throughput intestinal sampling with sealed containment and target drug delivery, we developed a dual‐functional ingestible passive capsule with a dual‐triggered control system based on pH‐response and mechanical actuation.

Cooperative Rh2(OAc)4/Chiral Phosphoric Acid‐Catalyzed (3 + 3)‐Cycloadditions of Pyrrole‐3‐Methides and Carbonyl Ylides

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A stereoselective one‐step (3 + 3)‐cycloaddition between in situ generated pyrrole‐3‐methides and carbonyl ylides has been developed using cooperative rhodium and chiral phosphoric acid catalysis. The reaction affords oxa‐bridged cyclohepta[1,2‐b]pyrroles bearing three stereogenic centers, including two quaternary ones, in high yields and ...
