Correction: Asymmetric catalytic [1,3]- or [3,3]-sigmatropic rearrangement of 3-allyloxy-4H-chromenones and their analogues

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.
