| Abstract: | Cyclopropanone derivative 1-(arylsulfonyl)cyclopropanol 4 simply prepared from the reaction of cyclopropanone ethyl hemiacetal 3 with sodium arylsufinate in the presence of formic acid is a new cyclopropanone equivalent to react with terminal acetylenes, and disubstituted amines in water catalyzed by AuCl3, to provide an unprecedented synthesis of 1-alkynyl cyclopropylamines in moderate yields. |
