摘要:
Discover nickel! A nickel-catalyzed alkenylative cyclization of 1,6-enynes and alkenyl boronic acids affording substituted pyrrolidines and dihydrofurans is described (see scheme; cod=1,5-cyclooctadiene, Ts = p-toluene sulfonate). The reaction is highly chemo- and stereoselective. A possible reaction mechanism involving a nickelacyclopentene intermediate is proposed. Copyright © 2013 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
