Cyclization
摘要:
AbstractA novel method has been developed for the synthesis of 3‐pyrrolines from β‐ketopropargylamines via a 5‐endo‐dig carbocyclization. This transformation involves a silver‐catalyzed Conia‐ene type reaction tolerating broad substrate scope with good to excellent yields. Furthermore, this methodology has been extended for the construction of 2‐substituted pyrroles under base‐mediated conditions.magnified image
