Ruthenium-Catalyzed Hydrovinylation of N-Acetylenamines Leading to Amines with a Quaternary Carbon Center
摘要:
A catalytic hydrovinylation of N-acetylenamines with ethylene is reported. This new hydrovinylation reaction is catalyzed by a ruthenium hydride complex, RuHCl(CO)(PCy3)(2), providing a series of N-acetylamines with a quaternary carbon center with up to 99% yield.

Palladium-catalysed arylative cyclisation of N-allylacetamides with aryl halides yielding benzyl-substituted oxazolines
Treatment of N-allylacetamide with aryl halide in the presence of sodium t-butoxide and a palladium catalyst leads to arylative cyclisation to provide the corresponding benzyl-substituted oxazoline in high yield.
