Nitrones as Versatile Linkages for the Construction of Covalent Organic Polymers by Tandem Transformations

open access: yesChemistryEurope, EarlyView.
The nitrone moiety's versatility in covalent organic polymer (COP) materials is shown by its ability to form either nitrone‐linked or oxime O‐ether‐linked COPs from the same building blocks, simply by changing reaction conditions. Additionally, its 1,3‐dipolar cycloaddition reactivity enabled the synthesis of a functionalized isoxazolidine‐linked ...

Preparation of Enantioenriched Spirocyclic Scaffolds Transferring Axial Chirality from Borylalkylidenecycloalkanes

open access: yesChemistryEurope, EarlyView.
Enantiomerically enriched borylalkylidenecycloalkanes can transfer axial chirality to spirocyclic compounds with central chirality, without erosion of enantiomeric ratio. The method involves cyclopropanation, borylcyclopropanation, epoxidation, and aziridination reactions, that proceed in astereodivergent manner giving access to spirocycles with ...
