  2. 1. Synthesis of Polyhydroxylated Surfactants : Comparison of Surfactant Stereoisomers and Investigation of Haemolytic Activity

    Author : Kristina Neimert-Andersson; Peter Somfai; Krister Holmberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Polyhydroxy surfactants; Sugar surfactants; Dihydroxylation; Metathesis; Langmuir monolayers; Chiral discrimination; Haemolysis; Organic chemistry; Organisk kemi;

    Abstract : I den här avhandlingen har vi studerat hur man kan göra nya tensider. En tensid är en speciell molekyl som har förmågan att lösa sig i både vatten och olja. Man kan göra följande experiment hemma: Fyll en glasburk till hälften med vatten och tillsätt en droppe matolja. READ MORE

  4. 2. The three-component aza-Baylis-Hillman reaction : development and application

    Author : Daniela Balan; Hans Adolfsson; Varinder Aggarwal; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; Organisk kemi;

    Abstract : The current thesis presents the optimization and generalization of the Baylis-Hillman reaction applied to in situ generated imines, i.e. a three-component aza- Baylis-Hillman reaction. We found that the title reaction proceeds most efficiently in the presence of a combination of catalysts, i. READ MORE

  5. 3. Amino Aacohols : stereoselective synthesis and applications in diversity-oriented synthesis

    Author : Staffan Torssell; Peter Somfai; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Organic chemistry; amino alcohol; carbenoid; carbonyl ylide; cross-metathesis; diastereoselective; 1; 3-dipolar cycloaddition; sphingosine; Organisk kemi; Organic chemistry; Organisk kemi;

    Abstract : This thesis is divided into three separate parts with amino alcohols as the common feature. The first part describes the development of a novel three-component approach to the synthesis of α-hydroxy-β-amino esters. READ MORE

  6. 4. Stereoselective Synthesis of Amino Alcohols : Applications to Natural Product Synthesis

    Author : Staffan Torssell; Peter Somfai; Pher G Andersson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Amino alcohol; asymmetric 1.3-dipolar cycloaddition; azomethine ylide; carbenoid; carbonyl ylide; cross-metathesis; omuralide; oxazolidine; rhodium; sphingosine; stemoamide; stereoselective synthesis; total synthesis.; Organic chemistry; Organisk kemi;

    Abstract : This thesis is divided into four separate parts with amino alcohols as the common feature. The first part of the thesis describes the development of an efficient three-component approach to the synthesis of α-hydroxy-β-amino esters. READ MORE

  7. 5. Carbocation Catalysis for Organic Synthesis

    Author : Shengjun Ni; Johan Franzén; Bernd Plietker; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; carbocation; trityl cation; Lewis acid catalyst; enantioselective; chiral counteranion; oxa-Diels–Alder; bromination; aldehyde–olefin metathesis; Kemi; Chemistry;

    Abstract : The most common view of carbocations in organic chemistry is that they are short-lived intermediates in several fundamental reactions, e.g. the classic SN1-reaction. READ MORE
