Cu(I)-Catalyzed Three-Component Reaction of Propargylic Alcohol, Secondary Amines and Atmospheric CO2

beta-Oxopropylcarbamates constitute an important kind of organic compounds, owing to the extensive applications in agrochemicals, pharmaceuticals, organic synthesis, and protection of amino group. In this article, an efficient and atom-economical Cu(I) catalyzed three-component reaction of propargylic alcohols, secondary amines and CO2 has been developed under atmospheric pressure, affording various beta-oxopropylcarbamates in high yields with high selectivity by controlling the concentration of O-2. This protocol avoids the use of high pressure of CO2 and provides an extremely simple way to access the synthetically useful beta-oxopropylcarbamates.
