Correction for ‘Diastereoselective synthesis of 1,3-disubstituted isoindolines and sultams via bronsted acid catalysis’ by Ye Tao et al., Chem. Commun., 2018, 54, 11292–11295.


The authors regret that the intermediates identified as 21 and 23, 25, 26, 27, 28 and 29 in Schemes 3–5 and Table 2 are not alkynes as indicated in the original article, but rather cyclized 5-member rings with an exocyclic double bond. The subsequent reaction with triethylsilane then provides the title compounds by diastereoselective reduction. Corrected versions of Table 2 and Schemes 3–5 are shown below. The structures have also been corrected in the ESI of the original article, which is available online.
