Copper-catalyzed N=H insertion and oxidative aromatization cascade: Facile synthesis of 2-arylaminophenols

A copper-catalyzed cascade reaction of N-H insertion and oxidative aromatization has been developed. 2-Arylaminophenols have been prepared in moderate to high yields from the diazo substrates. Moreover, this newly established methodology allows efficient access to natural 1-oxygenated carbazole alkaloids, such as glycozolicine and murrayafoline A. Copper falls: A copper-catalyzed cascade reaction of N=H insertion and oxidative aromatization yields 2-arylaminophenols. This newly established methodology also allows efficient access to natural 1-oxygenated carbazole alkaloids, such as glycozolicine and murrayafoline A.

Copper-catalyzed direct synthesis of di- and triphenylamines: A dramatic accelerating effect of 2-aminophenols

Utilizing the dramatic accelerating effect of 2-aminophenols, we developed a copper-catalyzed system for the selective synthesis of di- and triphenylamines. In addition, N- and O-arylation could be achieved in coupling reactions between 2-aminophenol and nitroaryl halides. A copper-catalyzed system for the selective synthesis of di- and triphenylamines has been developed. This new protocol provides a direct and efficient way to synthesize o-hydroxy-substituted di- and triphenylamines. Copyright

Cyclic di[(o-polyethyleneglycoxy)phenyl]amine: New members in the crown ether family

The synthesis of cyclic ethers based on polyethyleneglycol chains grafted on di(o-hydroxyphenyl)amine is described. The starting diarylamine is obtained from a melted salt procedure and coupled to the tosylated tri-, tetra- and pentaethyleneglycol. The X-ray crystal structure of the tetraethyleneglycol derivative was determined. For the triethyleneglycol compound, alkylation of the nitrogen atom with 5-bromomethyl-5'-methyl-2,2'- bipyridine (excess or 1 equiv.) led either to the quaternary ammonium salt or to the tertiary amine derivatives, respectively. The latter reacted with [Re(CO)5Cl] to give the corresponding Re(I) complex in a facial configuration. (C) 2000 Elsevier Science Ltd.
