Gold-catalyzed endo-cyclizations of 1,4-diynes to seven-membered ring heterocycles
"Chemical Equation Presented" endo-Ruie for gold: A highly endoselective gold-catalyzed cycloisomerization of 1,4-diynes was developed. By employing electron-rich phosphines and N-heterocyclic carbenes as ligands, a number of 1,4-diynes could be cyclized
