Correction to: Nature Chemistry https://doi.org/10.1038/s41557-022-00893-5, published online 17 February 2022.

In the version of this article initially published, a conversion process led to label alignment errors in Figs. 1a, 2b, 3d, 5b–d and 6b,c and in Tables 1 and 2. There were also errors in functional groups in the two structures of the difluoro analogues of rumenic ester in the top right of Fig. 2b; in the top structure, “MeO2C” first appeared as “H2CO2Me”, and in the bottom structure, “CO2Me” initially appeared as “MeO2CH2”. The errors have been corrected in the HTML and PDF versions of the article.
