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.

Anodic olefin couplingreactions using a tosylamine trapping group have been studied. The cyclizations are favored by the use of a less-polar radical cation and more basic reaction conditions. The most significant factor for obtaining good yields of cyclic product is the use of the more basic reaction conditions. However, a number of factors including the nature of both the solvent and the electrolyte
