A one-pot construction of bicyclo[3.2.1]oct-6-ene frameworks involved gold-catalyzed (4 + 3)-cycloadditions between 2-(1-alkynyl)-2-alken-1-ones and substituted cyclopentadienes; diastereoselectivity (dr >25:1) and enantioselectivity (up to 99.9% ee) were achieved with a chiral gold catalyst. DFT calculations suggested a three-step ionic mechanism for the cycloadditions of gold-containing 1,3-dipoles with cyclopentadienes, in which an exo-spatial arrangement was preferable. In the experiment, the researchers used many compounds, for example, 3-Phenyl-1-(thiophen-2-yl)prop-2-en-1-one (cas: 3988-77-0COA of Formula: C13H10OS).
3-Phenyl-1-(thiophen-2-yl)prop-2-en-1-one (cas: 3988-77-0) belongs to benzothiophene derivatives. Benzothiophene is a fused ring compound of thiophene ring and benzene ring, which is an important class of heterocycles with advantageous structures. Due to its aromaticity, thiophenes do not exhibit the same properties as conventional thioethers.COA of Formula: C13H10OS
