  2. 1. 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
