Synthesis of 1,2-phenylenediamine capturing molecule for the detection of diacetyl

open access: yesData in Brief, 2017
Here we describe the design of 1,2-phenylenediamine capturing molecule and the synthesis steps necessary for its preparation. The designed 1,2-phenylenediamine derivative is able to capture diacetyl in solution, as shown by ESIMS, forming a chemical ...

Unilateral Ankle‐Foot Exoneuromusculoskeleton with Balance‐Sensing Feedback for Self‐Help Telerehabilitation after Stroke

open access: yesAdvanced Robotics Research, EarlyView.
This study introduces a hybrid robot that integrates mechanical assistance by musculoskeletons (i.e., soft pneumatic muscle with rigid exoskeletal extensions), neuromuscular electrical stimulation, and vibrotactile feedback in a lightweight wearable mechatronic complex applicable to the paretic ankle–foot poststroke for gait restoration. The system can

Multiphoton Multicomponent Reactions: Discovery of the 2‐Photon Ketene 4‐Component Reaction (2P‐K‐4CR)

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Multicomponent reactions triggered by multiple photons: complex heterocycles can be synthesized in a regio‐ and stereoselective manner via a double photoactivation using visible light from simple building blocks, exploiting the combination of ketene 3‐component reaction and Paternò–Büchi cycloaddition.

Asymmetric Synthesis of Highly Substituted Spiro[2H‐pyrrole‐2,3‐Succinimide] Derivatives by Copper‐Catalyzed Post‐Ugi Reactions

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
Abstract Herein we present a novel one‐pot methodology for the synthesis of enantioenriched 2H‐pyrrolespirosuccinimides by copper‐catalyzed reactions on Ugi adducts derived from enantiopure α‐alkylbenzyl amines through a chirality transfer process. We have proposed a mechanism, supported by density functional theory (DFT) calculations, where a hydrogen

Dual Photoredox/Cu‐Catalysis Enables Diastereoselective Synthesis of 3‐β‐Ethynyltropanes via Decarboxylative Alkynylation

open access: yesAdvanced Synthesis &Catalysis, EarlyView.
A copper‐catalyzed decarboxylative alkynylation of tropanes is developed. This approach works under mild conditions and selectively produces a range of 3‐β‐alkynylated tropanes. Moreover, it provides a versatile and convergent platform for further functionalization of the triple bond.
