Studies Of The Solid-Phase Pauson-Khand Reaction Selective In-Situ Enone Reduction To 3-Azabicyclo[3.3.0]Oct-Anones, Daniel Becker, Daniel L. Flynn Feb 2016

Studies Of The Solid-Phase Pauson-Khand Reaction Selective In-Situ Enone Reduction To 3-Azabicyclo[3.3.0]Oct-Anones, Daniel Becker, Daniel L. Flynn

Daniel P. Becker

The Smit-Caple DSAC Pauson-Khand cyclization of a series of N-protected allyl propargyl amines in the absence of oxygen gave rise to formation of the saturated azabicyclo[3.3.0]octanones in excellent yields. Standard cyclization in air gave mixtures of saturated and unsaturated ketones.

Synthesis Of N-Boc-3-Azabicyclo[3.3.0]Octan-7-One Via Reductive Pauson-Khand Cyclization And Subsequent Conversion To A Novel Diazatricyclic Ring System, Daniel Becker, Daniel L. Flynn Feb 2016

Synthesis Of N-Boc-3-Azabicyclo[3.3.0]Octan-7-One Via Reductive Pauson-Khand Cyclization And Subsequent Conversion To A Novel Diazatricyclic Ring System, Daniel Becker, Daniel L. Flynn

Daniel P. Becker

An intramolecular reductive Pauson-Khand reaction of the hexacarbonyldicobalt complex of N-(tert-butyloxycarbonyl)allylpropargylamine under dry-state adsorption conditions directly afforded the saturated N-BOC-3-azabicyclo[3.3.0]octan-7-one when the reaction was performed under an inert atmosphere. This bicyclic ketone was converted in several steps to the novel octahydro-1-azeto[2′,3′:3,4]cyclopenta[1,2-C]pyrrole ring system as confirmed by single crystal X-ray analysis.

The Separation And Analysis Of Symmetric And Asymmetric Dimethylarginine And Other Hydrophilic Isobaric Compounds Using Aqueous Normal Phase Chromatography, Seiichiro Watanabe Dec 2015

The Separation And Analysis Of Symmetric And Asymmetric Dimethylarginine And Other Hydrophilic Isobaric Compounds Using Aqueous Normal Phase Chromatography, Seiichiro Watanabe

Seiichiro Watanabe

Two biologically important compounds with clinical relevance, asymmetric dimethylarginine and symmetric dimethylarginine, are analyzed using aqueous normal phase chromatography on silica hydride-based columns. Two different stationary phases were tested, a commercially available Diamond Hydride™ and a 2-acrylamido-2-methylpropane sulfonic acid experimental column. Two types of analytical protocols were investigated: analysis of the compounds when separation was achieved and analysis of the compounds with partial chromatographic separation. Urine samples from tuberculosis patients were tested for levels of asymmetric and symmetric dimethylarginine. The mass spectrometric technique of in-source fragmentation that can provide data similar to a tandem mass analyzer was evaluated as a …
