Tandem Blaise-Alkenylation with Unactivated Alkynes: One-Pot Synthesis of α-Vinylated β-Enaminoesters from Nitriles
摘要:
The in situ generated Blaise reaction intermediate, a zinc bromide complex of beta-enaminoester, reacts with various unactivated terminal alkynes and an internal alkyne under mild conditions to afford alpha-vinylated beta-enaminoesters in good to excellent yields.
