N-Heterocyclic carbene-catalyzed [3 + 3] annulation of bromoenals with 2-aminochromones has been successfully developed. A structurally diverse set of chromeno[2,3-b]pyridinones was efficiently constructed in acceptable to excellent yields. The reaction features mild reaction conditions, a broad substrate scope, and easy scale-up.Correction for 'Significant field enhancements in an individual silver nanoparticle near a substrate covered with a thin gain film' by Jinhong Xian et al., Nanoscale, 2014, 6, 13994-14001, DOI 10.1039/C4NR036
