title: Silver-catalyzed cascade cyclization-stannylation of o-alkynylaniline derivatives with 2-tributylstannylfuran: an efficient synthesis of (3-indolyl)stannanes.
abstract: A straightforward synthesis of (3-indolyl)stannanes through silver-catalyzed cyclization-stannylation of N-electron-withdrawing group-substituted o-alkynylanilines in the presence of 2-tributylstannylfuran is developed. This method offers several advantages such as no requirement of additional ligands, high efficiency and a wide reaction scope.
