摘要: Rh(I)-catalysed hydrocarbonylation of alkynes 1 in the presence primary amines gives substituted 2-pyrrolidinones 3 a one-pot procedure. Replacement hydrogen by hydrosilanes via silylcarbonylation leads to 4-silylated 1-aza-1,3-butadienes 5. These azadienes are converted with dimethyl acetylenedicarboxylate 1,4-dihydropyridines 8 Diels-Alder reaction.
