    Notes: -Heterofunctionalised allylic ethers 1, silanes 5, and amines 9 are hydroformylated in the presence of primary or secondary amines 2 to form the corresponding γ-amino- and δ-amino-functionalised compounds. The rhodium(I)-catalysed reaction sequence proceeds by aldehyde formation and subsequent reductive amination to generate the corresponding functionalised secondary or tertiary amines. This selective one-pot hydroaminomethylation procedure establishes access to γ-amino- and δ-amino-functionalised ethers, amines or silanes with potential biological activity.

    Tandem Silylformylation/Wittig Olefination of Terminal Alkynes: Stereoselective Synthesis of 2,4-Dienoic Esters (2000)
    Weinheim : Wiley-Blackwell
    Liebigs Annalen 2000 (2000), S. 1131-1135 
    Details
    ISSN: 1434-193X
    Keywords: Carbonylation ; Wittig reactions ; Rhodium ; Homogeneous catalysis ; Chemistry ; General Chemistry

    Topics: Chemistry and Pharmacology
    Notes: -The rhodium(I)-catalysed sequential silylformylation/Wittig olefination of terminal alkynes with hydrosilanes and carbon monoxide in the presence of stabilised P-ylides leads to substituted 2,4-dienoic esters in a one-pot procedure. The α,β,γ,δ-unsaturated esters are generated with high (2E,4Z) stereoselectivity in good to excellent yields. Conversions of the products in [2+1] cycloaddition reactions are presented.
