Access to Highly Functionalized Indanes from Arynes and α,γ-Diketo Esters

Hu, Wanyao,Zhang, Cong,Huang, Jie,Guo, Yingying,Fu, Zhenqian,Huang, Wei

, p. 941 - 945 (2019)

An unprecedented method for the synthesis of highly functionalized indanes from arynes and α,γ-diketo esters is described. Importantly, mild and nearly pH-neutral conditions ensure excellent functional group tolerance. Theoretical studies indicated that t
