Abstract

Correction for ‘A visible light-mediated three-component strategy based on the ring-opening of cyclic ethers with aryldiazoacetates and nucleophiles’ by Mateus L. Stivanin et al., Org. Chem. Front., 2022, 9, 1321–1326, https://doi.org/10.1039/D1QO01780B.

The authors regret that the structure of compound 30 was incorrectly assigned, and therefore Scheme 5 was incorrect in the original manuscript. The corrected compound 30 and Scheme 5 are shown below.

Scheme 5 Representative nucleophiles evaluated in this photochemical strategy to react with aryldiazoacetate 1a and THF 3a. ^a NuH was used in excess (co-solvent).

Re-synthesizing molecule 30 in a larger scale, exactly as previously described, it was possible to observe that the oil initially formed led to the formation of a white solid (mp = 59–61 °C), which was recrystallized from a mixture of ethyl acetate/hexane to afford a crystal suitable for X-ray analysis, thus allowing the unambiguous assignment of the correct regioisomer (derived from an O-attack of the isoxazole-5-one ring).

We thank Julia A. O. Hansen and Dr Deborah Simoni (Unicamp, Brazil) for the confirmation of the structure of compound 30.

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