Abstract
| - A general and efficient Cu(I)-catalyzed cross-coupling reaction of terminal alkynes and monooxalyl chloride for the synthesis of 2-oxo-3-butynoates and 2-oxo-3-butynoamides was developed. Readily available startingmaterials, the mild reaction conditions, wide functionalgroup tolerance, and the obviation of stoichiometric organolithium or magnesium reagents combine to highlight thisreaction.
