Tandem β-enamino ester formation and cyclization with o-alkynyl anilines catalyzed by InBr3: Efficient synthesis of β-(N-Indolyl)-α,β-unsaturated esters

Murai, Kenichi,Hayashi, Shoko,Takaichi, Nobuhiro,Kita, Yasuyuki,Fujioka, Hiromichi

supporting information; experimental part, p. 1418 - 1421 (2009/06/28)

A tandem reaction providing β-(N-indolyl)-α,β-unsaturated esters from β-keto esters and o-alkynyl anilines was developed. Z-Alkenes were selectively formed due to the stability of the β-enamino ester as an intermediate of the reaction. This reaction inclu
