Correction to “Synthesis of 6/5/3-Fused Tricyclic Scaffolds via Multistep Cascade Cyclization of α-Aryl Vinylsulfoniums with para-Quinamines and para-Quinols”

Abstract

Metrics & MoreArticle Recommendations W e would like to add a new reference (would be ref 10 in our original work but labeled as ref 1 below) citing the published work of Zhu et al. Adv. Synth. Catal. 2024, 366 (13), 2939−2944, which also describes similar chemistry to our work. When we submitted our manuscript, the manuscript of Zhu et al. had just been published online, and it was inadvertently overlooked in our survey of the literature.In the conclusion paragraph, we add a reference (1):In conclusion, we have disclosed a straightforward approach to construct hydroindoline-5-one-based 6/5/3-fused polycyclic ring structures through multistep cascade reactions of paraquinamines and α-aryl vinylsulfoniums tetraphenylborate. In the presence of mild conditions, the reactions proceed smoothly to deliver the desired products in generally good yields. 1 This protocol is also applicable to para-quinols to furnish hydrobenzofuran-5-one-based 6/5/3-tricyclic scaffolds. Additionally, the scale-up synthesis and product derivatizations further highlight the protocol's potential for synthetic applications. Further investigations along this line are currently underway in our laboratory.
