  • Part I. the Total Synthesis Of
    AN ABSTRACT OF THE THESIS OF Lester Percy Joseph Burton forthe degree of Doctor of Philosophy in Chemistry presentedon March 20, 1981. Title: Part 1 - The Total Synthesis of (±)-Cinnamodialand Related Drimane Sesquiterpenes Part 2 - Photochemical Activation ofthe Carboxyl Group Via NAcy1-2-thionothiazolidines Abstract approved: Redacted for privacy DT. James D. White Part I A total synthesis of the insect antifeedant(±)-cinnamodial ( ) and of the related drimanesesquiterpenes (±)-isodrimenin (67) and (±)-fragrolide (72)are described from the diene diester 49. Hydro- boration of 49 provided the C-6oxygenation and the trans ring junction in the form of alcohol 61. To confirm the stereoselectivity of the hydroboration, 61 was convertedto both (t)-isodrimenin (67) and (±)-fragrolide (72) in 3 steps. A diisobutylaluminum hydride reduction of 61 followed by a pyridiniumchlorochromate oxidation and treatment with lead tetraacetate yielded the dihydrodiacetoxyfuran102. The base induced elimination of acetic acid preceded theepoxidation and provided 106 which contains the desired hydroxy dialdehydefunctionality of cinnamodial in a protected form. The epoxide 106 was opened with methanol to yield the acetal 112. Reduction, hydrolysis and acetylation of 112 yielded (t)- cinnamodial in 19% overall yield. Part II - Various N- acyl- 2- thionothiazolidineswere prepared and photo- lysed in the presence of ethanol to provide the corresponding ethyl esters. The photochemical activation of the carboxyl function via these derivatives appears, for practical purposes, to be restricted tocases where a-keto hydrogen abstraction and subsequent ketene formation is favored by acyl substitution.

  • Reductive Amination with [11C]Formaldehyde: a Versatile Approach to Radiomethylation of Amines
    International Journal of Organic Chemistry, 2012, 2, 202-223 http://dx.doi.org/10.4236/ijoc.2012.23030 Published Online September 2012 (http://www.SciRP.org/journal/ijoc) Reductive Amination with [11C]Formaldehyde: A Versatile Approach to Radiomethylation of Amines Chunying Wu1, Ruoshi Li1, Dorr Dearborn2, Yanming Wang1* 1Division of Radiopharmaceutical Science, Case Center for Imaging Research, Department of Radiology, Cleveland, USA 2Environmental Health, Case Western Reserve University, Cleveland, USA Email: *[email protected] Received February 16, 2012; revised March 24, 2012; accepted April 2, 2012 ABSTRACT Carbon-11 radiolabeled amines constitute a very important class of radioligands that are widely used for positron emis- 11 sion tomography (PET) imaging. Radiolabeling of amines is often achieved through radiomethylation using [ C]CH3I 11 or [ C]CH3OTf under basic conditions in a strictly anhydrous environment. Functional groups such as hydroxyl and carboxyl groups that are often present in the molecules are normally base sensitive and require protection and deprotec- tion, which substantially prolongs and complicates the radiolabeling process. Here we report a versatile approach to a series of C-11 radiolabeled amines prepared through reductive amination using [11C]formaldehyde. Using a variety of substrates bearing different functional groups, we demonstrate the general utility of this method. In contrast to conven- tional radiomethylation methods, the reductive amination using [11C]formaldehyde can be carried out in an aqueous environment relatively quickly without the need of protection of base-sensitive functional groups. Keywords: C-11 Formaldehyde; Radiomethylation; Reductive Amination; Positron Emission Tomography; Radiolabelling 1. Introduction probes must be labeled with positron-emitting radionu- clides such as carbon-11 or fluorine-18.

  • Aminolink™Reductant
    INSTRUCTIONS AminoLink ™ Reductant (s odium cyanoborohydride, NaCNBH ) 3 1291.3 44892 Number Description 44892 AminoLink Reductant (sodium cyanoborohydride, NaCNBH3), 2 × 1g Form: white to yellow crystalline powder; may yield slightly hazy solution in water Molecular Weight: 62.84 CAS # 25895-60-7 Caution: NaCNBH3 is toxic and must be used in a fume hood. See the Material Safety Data Sheet (MSDS) for additional information. Storage: Upon receipt store desiccated at room temperature. Product shipped at ambient temperature. Introduction Thermo Scientific AminoLink Reductant promotes the formation of stable bonds between aldehyde- and amine-containing molecules, enabling efficient labeling, conjugation and immobilization of proteins and other research molecules. Carbonyl groups such as aldehydes, ketones and glyoxals react spontaneously with amino groups to form Schiff base intermediates that are in equilibrium with their free forms. The interaction is pH-dependent, being somewhat more efficient in acidic conditions and especially strong at high pH. Addition of AminoLink Reductant (sodium cyanoborohydride) to a reaction in which Schiff base formation has occurred results in complete reduction of the labile Schiff base intermediate to a chemically stable bond1 (Figure 1). Unlike sodium borohydride, sodium cyanoborohydride is sufficiently mild to avoid adversely reducing aldehydes to nonreactive hydroxyls. The overall reaction of carbonyl groups to primary amino groups using sodium cyanoborohydride is called reductive amination. Immobilization by reductive amination of amine-containing biological molecules onto aldehyde-containing solid supports is used to create matrices for affinity purification of antibodies and other molecules. For detailed immobilization procedures, consult the instructions for AminoLink Plus Coupling Resin or the AminoLink Plus Immobilization Kit (see Related Thermo Scientific Products).

Lithium aluminium hydride (LiAlH4) Most reductions of carbonyl compounds are done with reagents that transfer a hydride from boron or aluminium. Sodium borohydride is a mild reducing reagent that rapidly reduce aldehyde and ketones but not esters. Lithium aluminium is strongly donor reagent and it rapidly reduce ester acids, nitriles, amides as well as aldehyde and ketones. Neither sodium borohydride nor lithium aluminium hydride reacts with isolated carbon- carbon double bonds. There reagents are nucleophilic and as such they normally attack polarized multiple bond such as C=O, CN by transfer of hydride ion to the more positive atom.

  • A Novel Carbohydrate Labeling Method Utilizing Transfer Hydrogenation-Mediated Reductive Amination
    A NOVEL CARBOHYDRATE LABELING METHOD UTILIZING TRANSFER HYDROGENATION-MEDIATED REDUCTIVE AMINATION Zsuzsanna Kovács1, Gábor Papp2, Henrietta Horváth3, Ferenc Joó2,3 and András Guttman1 1Horváth Csaba Laboratory of Bioseparation Sciences, University of Debrecen, Hungary 2Department of Physical Chemistry, University of Debrecen, Hungary 3MTA-DE Homogeneous Catalysis and Reaction Mechanisms Research Group, University of Debrecen, Hungary Abstract One of the most frequently used high-resolution glycan analysis methods in the biopharmaceutical and biomedical fields is capillary electrophoresis with laser-induced fluorescence (CE-LIF) detection. Glycans are usually labeled by reductive amination with a charged fluorophore containing a primary amine, which reacts with the aldehyde group at the reducing end of the glycan structures. In this reaction, first a Schiff base is formed that is reduced to form a stable conjugate by a hydrogenation reagent, such as sodium cyanoborohydride. In large scale biopharmaceutical applications, such as clone selection for glycoprotein therapeutics, hundreds of reactions are accomplished simultaneously, so the HCN generated in the process poses a safety concern. To alleviate this issue, here we propose catalytic hydrogen transfer from formic acid catalyzed by water-soluble iridium(III)- and ruthenium(II)-phosphine complexes as a novel alternative to hydrogenation. The easily synthesized water-soluble iridium(III) and the ruthenium(II) hydrido complexes showed high catalytic activity in carbohydrate labeling. This procedure is environmentally friendly and reduces the health risks for the industry. Using carbohydrate standards, oligosaccharides released from glycoproteins with highly sialylated (fetuin), high mannose (ribonuclease B) and mixed sialo and neutral (human plasma) N-glycans, we demonstrated similar labeling efficiencies for iridium(III) dihydride to that of the conventionally used sodium cyanoborohydride based reaction.
