Abstract
Correction for ‘Assembly of fluorinated chromanones via enantioselective tandem reaction’ by Mengxue Lu et al., Chem. Commun., 2021, 57, 4722–4725, DOI: 10.1039/D1CC01187A.
The authors regret that the structure of compound 3an was incorrect in Scheme 4 of the original article, the graphical abstract image, and the supplementary information. None of the scientific conclusions or discussion relating to this structure are affected. The correct structure is shown here in the corrected Scheme 4. The graphical abstract and supplementary information have been updated online accordingly.

Scheme 4 Substrate scope of the reaction between α,β-unsaturated aldehydes 2 and 2-F-1-(2-hydroxyphenyl)-1,3-butanedione 1a. The reactions were carried out with 1a (0.2 mmol), 2 (0.24 mmol), chiral amine C2 (5 mol%) and salicylic acid (20 mol%) in toluene (0.1 M) at r.t. for 48 h, followed by acylation in the presence of NEt3 (2 equiv.), acetyl chloride (1.5 equiv.) and DMAP (0.1 equiv.) in CH2Cl2 (4.0 mL) for 3 h. Yield refers to isolated yield, >19![[thin space (1/6-em)]](https://www.rsc.org/images/entities/char_2009.gif) :1 d.r. was determined by 1H NMR and 19F NMR of the crude products. ee value was determined by HPLC analysis. | ||
