  1. 1. Stereoselective Synthesis of Amino Alcohols : Applications to Natural Product Synthesis

    Författare :Staffan Torssell; Peter Somfai; Pher G Andersson; KTH; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER
