Thesis (Ph.D.)--The University of Wisconsin - Madison, 2007.
A general and efficient method for the coupling of a wide range of amides with alkynyl bromides is described here. 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 ynamides including macrocyclic amides via an intramolecular amidation.Subjects--Topical Terms:

A general and efficient method for the coupling of a wide range of amides with alkynyl bromides is described here. 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 ynamides including macrocyclic amides via an intramolecular amidation.

$a
Both intermolecular and intramolecular Rh(I)-catalyzed [4+2] cycloadditions of ynamides were developed, leading to interesting anilides and indolizidines compounds.

$a
A Bronsted acid-catalyzed highly stereoselective cyclization of arene-ynamides through a novel keteniminium intermediate was developed. And this methodology has been applied to the total syntheses of (+/-)-10-Desbromoarborescidine A.

$a
A one-pot synthesis of amide-substituted triazoles from alkyl bromides and amides is described here along with syntheses of novel bis-ynamides and their applications in [3+2] cycloadditions with azides to construct unique bis-triazoles.

$a
Tandem azidination- and hydroazidination Huisgen [3+2] cycloadditions of ynamides are described here. These processes are regioselective and chemoselective, leading to the syntheses of chiral amide-substituted triazoles.

A tandem azide-[3+2]-vinyl copper trapping employing ynamides and applications of these triazoles as templates for ring-closing metathesis are described here, combining the two powerful reactions to construct novel fused-triazoles and bridged-triazoles.

A copper(I)-catalyzed highly regioselective dipolar [3+2] cycloadditions of ynamides and nitrile oxides was described here, leading to novel 5-amino isoxazoles.

$a
A copper(I)-catalyzed highly diastereoselective Kinugasa reaction of ynamides and nitrones was described here, leading to various cis-alpha-amino-beta-lactams, which are very important compounds in medicine and chemistry.
