Umpolung Activation of Bicyclobutanes via N‐Heterocyclic Carbene Catalysis

open access: yesAngewandte Chemie, Volume 137, Issue 41, October 6, 2025.
NHC‐catalyzed umpolung of bicyclo[1.1.0]butane (BCB) aldehydes enables nucleophilic cycloaddition with carbonyls and imines to form bicyclic lactones and lactams. The resulting oxa‐ and aza‐bicyclo[3.1.1]heptane products can be further transformed into valuable rigid 3D scaffolds, offering a simple and versatile approach to access new chemical space ...
