Synthesis of Pyrrolidines and Piperidines via Palladium-Catalyzed Coupling of Vinylic Halides and Olefinic Sulfonamides
摘要:
The palladium-catalyzed coupling of vinylic halides and olefinic sulfonamides affords good yields of 2-(1-alkenyl)pyrrolidine and -piperidine sulfonamides via vinylpalladium addition to the olefin, regioselective rearrangement to a pi-allylpalladium intermediate, and subsequent intramolecular nucleophilic displacement of palladium.
