Enantioselective Palladium-Catalyzed Domino Carboetherification Reaction: Access to Isoxazoline-Linked Bis-Heterocycles.

Herein, we present an enantioselective domino carboetherification of β,γ-unsaturated oxime derivatives under mild reaction conditions. This process, catalyzed by palladium in combination with Sadphos ligands, offers a concise and highly efficient route for the assembly of chiral isoxazoline-linked methylenedihydrobenzofuran and methyleneindolin bis-heterocyclic scaffolds. The methodology demonstrates excellent functional group tolerance, a broad substrate scope, and high chemoselectivity and enantioselectivity.

High-resolution real-time 360° 3D model reconstruction of a handheld object with fringe projection profilometry.

The digitization of the complete shape of real objects has essential applications in fields of intelligent manufacturing, industrial detection, and reverse modeling. In order to build the full geometric models of rigid objects, the object must be moved relative to the measurement system (or the scanner must be moved relative to the object) to obtain and integrate views of the object from all sides, which not only complicates the system configuration but makes the whole process time-consuming. In this Letter, we present a high-resolution real-time 360° three-dimensional (3D) model reconstruction method that allows one to rotate an object manually and see a continuously updated 3D model during the scanning process.
