Formation of cinnoline derivatives by a gold(I)-catalyzed hydroarylation of N-propargyl-N′-arylhydrazines
摘要:
A study concerning the gold(I)-catalyzed hydroarylation of N-propargyl-N'-arylhydrazinecarboxylic acid methyl esters is described. The use of the gold complex [XPhosAu(NCCH(3))SbF(6)] as the catalyst in refluxing nitromethane allows the generally rapid and efficient synthesis of a range of functionalized 4-exo-methylene-1,2-dihydrocinnolines.

Nucleophilic substitutions of the benzene ring proceed with aromatic amines and alcohols under mild conditions. The attack of aliphatic amines may be directed to the aromatic core as well as to the carbonyl unit leading to azocarboxamides. The benzene ring can further be modified through radicalreactions, in which the tert-butyloxycarbonylazo group enables the generation of aryl radicals at either elevated
