  4. 7. Stereoselective Nucleophilic Additions to α-Amino Aldehydes: Application to Natural Product Synthesis

    Author : Per Restorp; Peter Somfai; Timothy J. Donohoe; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Stereoselective synthesis; Substrate-control; α-Amino aldehydes; Mukaiyama aldol; Allylsilanes; [3 2]-Annulation; -Alexine; DGDP; Vinyl epoxides; Regioselectivity; Alkyne nucleophiles; Organic chemistry; Organisk kemi;

    Abstract : This thesis deals with the development and application of new synthetic methodology for stereo- or regioselective construction of carbon-carbon bonds in organic synthesis. The first part of this thesis describes the development of a divergent protocol for stereoselective synthesis of chiral aminodiols by employing Mukaiyama aldol additions to syn- and anti-α-amino-β-silyloxy aldehydes.

  5. 8. Bridging McMurry and Wittig in One-Pot : Olefins from Stereoselective, Reductive Couplings of Two Aldehydes via Phosphaalkenes

    Author : Juri Mai; Sascha Ott; Christian Müller; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbonyl olefination; reductive aldehyde coupling; stereoselective; organophosphorus; phosphaalkene; phosphanylphosphonate; Wittig; Horner-Wittig; Horner-Wadsworth-Emmons; McMurry; Kemi; Chemistry;

    Abstract : The formation of C=C bonds is of great importance for fundamental and industrial synthetic organic chemistry. There are many different methodologies for the construction of C=C bonds in the literature, but currently only the McMurry reaction allows the reductive coupling of two carbonyl compounds to form alkenes.

  7. 10. Selective conversion of alcohols to aldehydes over metal oxide catalysts

    Author : Mariano Massa; Avdelningen för kemiteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Nowadays, transition metal oxide catalysts are employed to a large extent in many chemical processes for the selective production of chemicals and intermediates. Although metal oxides are mostly known as oxidation catalysts, they can successfully catalyze a wide range of reactions, such as dehydration. READ MORE
