A Sequential Palladium-Catalyzed Alder-Ene-Reductive Amination Reaction
摘要:
Alkyne allyl alcohols are readily transformed into beta-amino ethyl alkylidene tetrahydrofurans or beta-amino ethyl alkylidene pyrrolidines in a Pd-catalyzed cycloisomerization-reductive amination sequence with remarkable chemoselectivity leaving benzyl groups and trisubstituted double bonds intact.
