Journal ArticleDOI
Allyl-, Allenyl-, and Propargyl-Transfer Reactions through Cleavage of CC Bonds Catalyzed by an N-Heterocyclic Carbene/Copper Complex: Synthesis of Multisubstituted Pyrroles†
Journal ArticleDOI
Silver-catalyzed intramolecular chloroamination of allenes: easy access to functionalized 3-pyrroline and pyrrole derivatives.
Masahiro Sai,Seijiro Matsubara +1 more
TL;DR: A 1,10-phenanthroline-ligated cationic silver complex allows the intramolecular chloroamination of allenes with N-chlorosuccinimide using 2,6-lutidine as a base and these products are useful synthetic intermediates and can be easily transformed into functionalized 3-pyrroline and pyrrole derivatives.
Journal ArticleDOI
Chiral Brønsted Acid as a True Catalyst: Asymmetric Mukaiyama Aldol and Hosomi-Sakurai Allylation Reactions.
Masahiro Sai,Hisashi Yamamoto +1 more
TL;DR: Highly diastereo- and enantioselective Mukaiyama aldol reaction catalyzed by a new chiral Brønsted acid, N-(perfluorooctanesulfonyl)thiophosphoramide, is described, which allows the asymmetric Hosomi-Sakurai allylation, which has been considerably challenging due to the low reactivity of allylsilanes.
Journal ArticleDOI
Copper-Catalyzed Reaction of Alkyl Halides with Cyclopentadienylmagnesium Reagent
TL;DR: Treatment of alkyl halides with cyclopentadienylmagnesium bromide in the presence of a catalytic amount of copper(II) triflate yielded the corresponding cyclopENTadienyated products in high yields, and hydrogenation of the products providedAlkyl-substitutedcyclopentanes.
Journal ArticleDOI
A heterogeneous Ru/CeO2 catalyst effective for transfer-allylation from homoallyl alcohols to aldehydes.
TL;DR: A simple heterogeneous Ru/CeO2 catalyst was found to be effective for transfer-allylation from homoallyl alcohols to aldehydes, followed by isomerization to give the saturated ketones in high yields.
