Copper-Mediated N-Cyclopropylation of Azoles, Amides, and Sulfonamides by Cyclopropylboronic Acid
摘要:
Reaction of azoles, amides, and sulfonamides in dichloroethane with readily available cyclopropylboronic acid in the presence of copper acetate and sodium carbonate afforded the N-cyclopropyl derivatives in good to excellent yields.
