Xu, Yi published the artcileVinylethylene Carbonates as α,β-Unsaturated Aldehyde Surrogates for Regioselective [3 + 3] Cycloaddition, Recommanded Product: 3-Acetylthiophene, the main research area is vinylethylene carbonate alpha beta unsaturated aldehyde regioselective cycloaddition; polysubstituted terphenyl preparation.
Herein, the authors report a novel stepwise addition-controlled ring size method, to access tetrahydropyrimidines through an operationally simple [3 + 3] cycloaddition of vinylethylene carbonates with triazinanes. The authors could also use this method for a [3 + 3] oxidative cycloaddition, which allows the facile synthesis of polysubstituted terphenyls under mild conditions. Mechanistic studies suggest that vinylethylene carbonates could generate α,β-unsaturated aldehydes as 3-carbon synthons for cycloaddition via a combination process of Pd-catalyzed decarboxylation and β-H elimination.
Organic Letters published new progress about [3+3] Cycloaddition reaction (regioselective). 1468-83-3 belongs to class benzothiophene, name is 3-Acetylthiophene, and the molecular formula is C6H6OS, Recommanded Product: 3-Acetylthiophene.
