Silver-Catalyzed 7-exo-dig Cyclization of Silylenolether-ynesulfonamides

Cyclization of silylenolether‐ynesulfonamides proceeds at ambient temperature under mild reaction conditions under silver catalysis. Bridged compounds were obtained exclusively through 7‐exo‐dig reactions. The protocol is applicable to a wide range of substrates, thus leading to azabicyclic framewor...
