Abstract

Correction for ‘Asymmetric catalytic [1,3]- or [3,3]-sigmatropic rearrangement of 3-allyloxy-4H-chromenones and their analogues’ by Yi Li et al., Chem. Sci., 2024, 15, 11005–11012, https://doi.org/10.1039/D4SC02201G.

The authors regret that an important reference that should be cited was missed in the original article; this reference is shown below as ref. 4. The corresponding revised text is as follows.

There are rare examples related to asymmetric catalytic C2-functionalization of 3-hydroxychromenones:1–4 one is a chiral Pybox–Sc(III)-complex-catalyzed formal [3,3]-rearrangement to construct 3,4-chromanediones by Porco and co-workers,1 and the other is chiral NHC-initiated formation of an α,β-unsaturated acyl azolium intermediate to perform Coates–Claisen rearrangement by Bode's group2 and Rafiński's group.3

Furthermore, other important compounds derived from kojic acid (5q), allomaltol (5r) and lawsone (5s) could be efficiently constructed in good yields (64–87%) and enantioselectivities (74–92% ee). These products were previously obtained via iridium-catalyzed allylic alkylation by Mukherjee et al.4

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