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

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

    Sammanfattning : 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.

    Sammanfattning : Targeted tumor therapy is to deliver cytotoxic agents selectively to tumor cells. By such delivery, normal tissues receive minimal damage while a therapeutical effect is achieved in tumor. A targetingsystem can be constructed by conjugating a tumor-seeking molecule and toxic agents via a carrier. LÄS MER

  4. 3. Carboligation using the aldol reaction : A comparison of stereoselectivity and methods

    Författare :Derar Al-Smadi; Mikael Widersten; Ulf Nilsson; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; aldol reaction; cinchonine; FSA enzyme; homologation reactions; phenylacetaldehyde derivatives; samarium diiodide.;

    Sammanfattning : The research summarized in this thesis focuses on synthesizing aldehyde and aldol compounds as substrates and products for the enzyme D-fructose-6-aldolase (FSA). Aldolases are important enzymes for the formation of carbon-carbon bonds in nature. LÄS MER
