A set of reactions involving copper-catalyzed trifluoromethylazidation and then rearrangement of aniline-linked 1,7-enynes with the relatively poorly reactive Togni reagent I and TMSN3 was developed, and provided facile access to structurally d
Silver-catalyzed cascade cyclization-stannylation of o-alkynylaniline derivatives with 2-tributylstannylfuran: An efficient synthesis of (3-indolyl)stannanes

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.
Coupling and cycloaddition of ynamides: Homo- and Negishi coupling of tosylynamides and intramolecular [4 + 2] cycloaddition of N-(o-ethynyl)phenyl ynamides and arylynamides

, p. 3843 - 3855 (2007/10/03)
N,N′-aryl- and N,N′-alkyl-buta-1,3-diyne-1,4-ditosylamides have been synthesized for the first time, in good to excellent yields, by copper-catalyzed dimerization of the corresponding N-aryl or N-alkyl tosylynamides. Negishi coupling of N-ethynylzinc tosy
Synthesis of carbazoles from ynamides by intramolecular dehydro Diels-Alder reactions
