Author Correction: A Cu(II)–ATP complex efficiently catalyses enantioselective Diels–Alder reactions

Correction to: Nature Communications https://doi.org/10.1038/s41467-020-18554-x, published online 22 September 2020.

The original version of this Article contained several errors with regards to the absolute configurations of 2’-OH and 3’-OH at ATP in the theoretical models. The errors can be found in Fig. 4a and Fig. 4b. The correct version of Fig. 4a and 4b is:

which replaces the previous incorrect version:

This has been corrected in both the PDF and HTML versions of the Article.

The associated Supplementary Figs. S22–S25 also contained the same error. The correct version of Supplementary Figures S22-S25 are:

Supplementary Fig. 22. The proposed models of Cu²⁺⋅ATP. The relative electronic energies are in the parenthesis with a unit of kcalmol⁻¹.

Supplementary Fig. 23. The precursors of the intermediates of 1a-Cu²⁺⋅ATP and 2 that yield the corresponding products 3a in different configurations. The relative electronic energies (ΔE) of the precursors are shown in the table.

Supplementary Fig. 24. The intermediates of 3a-ATP⋅Cu²⁺ and their relative electronic energies (ΔE).

Supplementary Fig. 25. The relative electronic energy profile of the reaction path for Cu²⁺⋅ATP-catalyzed Diels–Alder reaction of 1a and 2 that yields 3a (endo) in the absolute configuration of 1R, 2S, 3S, 4S. TS, transition state.

Due to the above errors, the text in the original version of this Article also contained errors. Page 5, right column incorrectly reads ‘The relative electronic energy (ΔE) of the optimised Cu^2+·ATP structure was 1.1 kcal mol⁻¹ lower than that of a previously described model obtained by a molecular orbital method⁵⁷ and 22.7 kcal mol⁻¹ lower than that of the Cu²⁺·ATP model without a hydrogen bond (Supplementary Fig. S22).’ and ‘the ΔE value of the precursor of 1a-Cu²⁺·ATP and 2 that yielded 3a (endo) via the attack of the Si face was 8.1 kcal mol⁻¹ lower than that of the precursor for the Re face attack (Fig. 4b).’ The correct version states ‘The relative electronic energy (ΔE) of the optimised Cu²⁺·ATP structure was 0.3 kcal mol⁻¹ lower than that of a previously described model obtained by a molecular orbital method⁵⁷ and 8.7 kcal mol⁻¹ lower than that of the Cu²⁺·ATP model without a hydrogen bond (Supplementary Fig. S22).’ and ‘the ΔE value of the precursor of 1a-Cu²⁺·ATP and 2 that yielded 3a (endo) via the attack of the Si face was 9.1 kcal mol⁻¹ lower than that of the precursor for the Re face attack (Fig. 4b).’

Page 6, left column incorrectly reads ‘However, the ΔE value of 3a (Re-exo) was 1.3 kcal mol⁻¹ lower than that of 3a (Si-exo), in accordance with the experimental results (Supplementary Figs. S21, S24).’ The correct version states ‘However, the ΔE value of 3a (Re-exo) was 2.6 kcal mol⁻¹ lower than that of 3a (Si-exo), in accordance with the experimental results (Supplementary Figs. S21, S24).’
