Abstract
Correction for ‘An intramolecular hydrogen bond-promoted “green” Ugi cascade reaction for the synthesis of 2,5-diketopiperazines with anticancer activity’ by Jie Li et al., RSC Adv., 2022, 12, 33175–33179, https://doi.org/10.1039/D2RA04958A.
The authors regret that it was not made clear in their original article that the X-ray crystal structure reported for product 5a, including the associated CIF file (CCDC 2009028), was not their own and was originally published by Meng Lan Lv et al. in 2020.1 The omitted reference is listed below.
The Electronic supplementary information (ESI) has been updated as there were errors in the crystallography data for 5a.
The authors sincerely apologise for these oversights.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
