Abstract
| - A mild, general, and efficient method for the synthesis of 2-monosubstituted and 2,5-disubstitutedfurans via the CuI-catalyzed cycloisomerization of alkynyl ketones was developed. It wasdemonstrated that furans containing both acid- and base-labile groups could be easily synthesizedusing this methodology. A plausible mechanism for this transformation is proposed.
