Correction to: Nature Chemistry https://doi.org/10.1038/s41557-018-0043-6, published online 21 May 2018.

In the version of this Article originally published, the word ‘stereoisomerism’ was erroneously included in the label of the upper-right box of Fig. 1. The label within the box has been corrected and it now reads: “Constitutional isomerism (same formula, different connectivity)”. This has been corrected in the online version of the Article.
