文摘Arylation of acrylamide and acrylonitrile were carried out with various arenediazonium tetrafluoroborates in the presence of a catalytic amount of Pd(OAc)(2) in ethanol and a variety of substituted (E)-cinnamamides and (E)-cinnamonitriles were obtained in high yields under mild reaction conditions.
文摘Two new cinnamamide derivatives designated as cimicifugamide((?))and isocimicifu- gamide((?)),have been isolated from the rhizomes of Cimicifuga dahurica(Turcz.)Maxim..Their structures were established based on spectral evidence as N-(3'-methoxy-4'-hydroxyphenethyl)- 4-0-β-D-galactopyrano syl-ferulamide(E)and N-(3'-methoxy-4'-hydroxyphenetnyl)-4-0-β-D-ga- lactopyranosyl-isoferulamide(Z)respectively.
