Journal ArticleDOI
Copper sulfate-pentahydrate-1,10-phenanthroline catalyzed amidations of alkynyl bromides. Synthesis of heteroaromatic amine substituted ynamides.
TL;DR: A practical cross-coupling of amides with alkynyl bromides using catalytic CuSO(4).5H(2)O and 1,10-phenanthroline is described here and provides a general entry for syntheses of ynamides including various new sulfonyl and heteroaromatic amine substituted ynamide.
Journal ArticleDOI
A copper-catalyzed C-N bond formation involving sp-hybridized carbons. A direct entry to chiral ynamides via N-alkynylation of amides.

TL;DR: A copper-catalyzed new C-N bond formation involving a sp-hybridized carbon is described here leading to a facile entry for syntheses of chiral ynamides, which should have a significant impact on the future development of synthetic methodologies employing ynamide.
Journal ArticleDOI
Copper(II)-catalyzed amidations of alkynyl bromides as a general synthesis of ynamides and Z-enamides. An intramolecular amidation for the synthesis of macrocyclic ynamides.

TL;DR: This novel amidation reaction involves a catalytic protocol using copper(II) sulfate-pentahydrate and 1,10-phenanthroline to direct the sp-C-N bond formation, leading to a structurally diverse array of ynamide including macrocyclic ynamides via an intramolecular amidation.
Journal ArticleDOI
The first stereoselective Ficini-Claisen rearrangement using chiral ynamides.
TL;DR: The first asymmetric Ficini−Claisen rearrangement using chiral ynamides was described in this article, which can be efficiently promoted by p-nitrobenzenesulfonic acid leading to high diastereoselectivity for a range of different allylic alcohols and CHs.
Journal ArticleDOI
A Rhodium(I)-Catalyzed Demethylation−Cyclization of o-Anisole-Substituted Ynamides in the Synthesis of Chiral 2-Amido Benzofurans§
Jossian Oppenheimer,Whitney L. Johnson,Michael R. Tracey,Richard P. Hsung,Peiyuan Yao,Renhe Liu,Kang Zhao +6 more
TL;DR: A Rh(I)-catalyzed demethylation-cyclization sequence for a direct transformation of o-anisole-substituted ynamides to benzofurans is described here.
