Copper-Catalyzed Iminoiodane-Mediated Aminolactonization of Olefins: Application to the Synthesis of 5,5-Disubstituted Butyrolactones
摘要:
A copper(I)-catalyzed reaction of a variety of 4-aryl-pent-4-enoates with nosyliminolodane generated in situ provides the corresponding 5-aryl-5. nosylamidomethylbutyrolactones. The reaction presumably proceeds via an aziridine intermediate, which could be isolated in one case.
