I found the field of Chemistry very interesting. Saw the article Gold(i)-NHC-catalysed synthesis of benzofuransviamigratory cyclization of 2-alkynylaryl ethers published in 2020. Recommanded Product: 104-21-2, Reprint Addresses Muchalski, H (corresponding author), Calif State Univ Fresno, 2555 E San Ramon Ave M-S SB70, Fresno, CA 93740 USA.. The CAS is 104-21-2. Through research, I have a further understanding and discovery of 4-Methoxybenzyl acetate
Homogeneous cationic gold(i) catalysis emerged as a preferred avenue for the activation of alkenes and alkynes towards reactions with weak nucleophiles, especially in cyclization reactions. Here we report an intramolecular carboalkoxylation reaction of electron-rich benzyl ethers of 2-ethynylaryl phenols catalysed by a digold(i)-NHC complex. The reaction proceeds efficiently with low catalyst loading and the resulting 2,3-disubstituted benzofurans form in moderate to good yields. Based on the results of a cross-over experiment, spectroscopic data, and DFT calculations, we propose a mechanism that accounts for the observed chemo- and regioselectivity.
