The hydroarylation of 3-arylprop-2-yn-1-amine derivatives with arylboronicacids has been studied in the presence of rhodium or palladium catalysts. By using a rhodium-based catalytic system, β,γ-diarylallylamines were isolated in good yields. By contrast, the formation of the regiosomeric γ,γ-diarylallylamines was achieved by means of a palladium catalyst in the presence of acetic acid. The complementary
The base-promoted cyclization of internal N-propargyl-malonamides in the presence of carbonate bases at room temperature or at 80 °C affords highly substituted 3-pyrrolin-2-ones in good yields.
在碳酸盐碱存在下,在室温或 80 °C 下,碱促进的内部 N-炔丙基-丙二酰胺环化以良好的收率提供了高度取代的 3-吡咯啉-2-酮。
