Page/Page column 54, (2010/02/14)
The present invention provides an industrially advantageous method of producing aminophenol compounds represented by the formula (1) by a simple and easy procedure at a high yield and a high purity. The present invention provides a method of producing an aminophenol compound represented by the formula (1): (wherein each of R1 and R2, which may be the same or different, is a hydrogen atom, a substituted or unsubstituted lower alkyl group or the like; R1 and R2, taken together with the adjacent nitrogen atom, may form a 5- or 6-membered heterocycle with or without other intervening heteroatoms; the heterocycle may be substituted by 1 to 3 substituents selected from the group consisting of a hydroxyl group, a substituted or unsubstituted lower alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted aryloxy group and the like; and the hydroxyl group in the formula (1) is substituted on the 2- or 4-position to the amino group on the phenyl ring), which comprises allowing a cyclohexanedione compound represented by the formula (2) to react with an amine compound represented by the formula (3) (wherein R1 and R2 are as defined above), under a neutral or basic condition.
Palladium/proazaphosphatrane-catalyzed amination of aryl halides possessing a phenol, alcohol, acetanilide, amide or an enolizable ketone functional group: Efficacy of lithium bis(trimethylsilyl)amide as the base
Urgaonkar, Sameer,Verkade, John G.
, p. 611 - 616 (2007/10/03)
A commercially available catalyst system comprising Pd(OAc)2 or Pd2(dba)3 and the proazaphosphatrane ancillary ligand P(i-BuNCH2CH2)3N (1) for the amination of aryl halides substituted with a phenol, alcohol, acetanilide, amide or ketone group containing an enolizable hydrogen is described. The reaction is performed in the presence of LiN(SiMe3)2 as the base. Other bases tested were either less effective or completely non-functional.
Improved functional group compatibility in the palladium-catalyzed synthesis of aryl amines
Harris, Michele C.,Huang, Xiaohua,Buchwald, Stephen L.
, p. 2885 - 2888 (2007/10/03)
(figure presented) The use of Pd2dba3 with bulky, electron-rich ligands 1 or 2 and LiN(TMS)2 as the base for the coupling of amines with aryl halides containing hydroxyl, amide, or enolizable keto groups is described. This protocol expands the utility of palladium-catalyzed C-N bond formation by allowing for the use of aryl halides containing these functional groups, obviating the need for protecting group manipulations.
