Abstract

Six-Membered Ring Formation from Lewis Acid Promoted Reactions of 2-Substituted 2-Alkenyl Amides and Esters of Ethenetricarboxylate. -Depending on the functionality of the substrates used, either saturated or unsaturated six-membered ring products are obtained selectively. The product formation is extensively investigated by DFT calculations. -(YAMAZAKI*, S.; UEDA, K.; FUKUSHIMA, Y.; OGAWA, A.; KAKIUCHI, K.; Eur. J. Org. Chem. 2014, 31, 7023-7033, http://dx.
