Correction: Ethanol-assisted mechanochemical asymmetric cross-dehydrogenative coupling reaction with recoverable chiral amine/NaCl for accessing chiral α-alkyl α-glycine derivatives

Abstract

Correction for ‘Ethanol-assisted mechanochemical asymmetric cross-dehydrogenative coupling reaction with recoverable chiral amine/NaCl for accessing chiral α-alkyl α-glycine derivatives’ by Jingbo Yu et al., Green Chem., 2024, https://doi.org/10.1039/d4gc00947a.

The authors regret that inaccuracies were present in the mechanism and associated discussion in the original article. In Scheme 4F, 1a and 2a were labelled incorrectly. The corrected Scheme 4 is shown below.

Scheme 4 Control experiments and plausible mechanism. (A) Mechanochemical reactions of 1a and 2a under a nitrogen atmosphere. (B) Radical trapping experiment. (C) Mechanochemical reaction of 1a and imine 1-1′. (D) Relationship between the ee values of C8 and 3aa. (E) Comparative reactions. (F) Proposed reaction mechanism. ^a Yields were those of the isolated products, ee values were determined by HPLC.

The following sentence within the main article should refer to 2a instead of 1a, and should read as follows:

“The enamine intermediate III is formed via the condensation of 2a with chiral amine C8, thus facilitating a stereoselective nucleophilic addition to intermediate II to give chiral intermediate IV.”

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
