Bis(indolyl)methanes are an important class of indole derivatives that have been widely used in medical treatments. A novel silver nitrate-catalysed one-potsynthesis of bis(indolyl)methanes has been developed. In the presence of silver nitrate, cycloisomerisation and bis-addition of o-ethynylanilines with aromatic aldehydes were carried out efficiently to afford the corresponding bis(indolyl)methanes
Silver-Catalyzed Tandem Ammonolysis-Cyclization of 2-Alkynylbenzenamines with Tetraalkylthiuram Disulfides to 4-Methylene-4H-benzo[d][1,3]thiazin-2-amines
In the presence of AgBF4, the ammonolysis-cyclization tandem reactions of various 2-alkynylbenzenamines with tetraalkylthiuram disulfides afforded the corresponding 4-methylene-4H-benzo[d][1,3]thiazin-2-amines in moderate to good yields.
