Heptafluorobutanoic acid

The cyclisation of -arylanthranilamides into acridones is effected by prolonged boiling with heptafluorobutanoic acid (M. Iwao. J.N. Reed and V. Snieckus, J. Amer. chem. Soc., 1982, 104, 5531). The particular significance of this work lies in the regiospecific -arylamination... [Pg.23]

By the reaction of theenolatc of camphor with carboxylic acid esters or chlorides, 1,3-diketones [better formulated as enols. such as (hydroxymethylene)camphor] are obtained. When trifluo-roacetic acid or heptafluorobutanoic acid are used, the corresponding diketones (abbreviated as tfc or hfc, respectively) have been successfully used as ligands for lanthanides and these are used as chiral shift reagents in NMR spectroscopy12. The complex Eu(hfc)3 [derived from ( + )-camphor)] 3 was used as a chiral catalyst for enantioselective Diels-Alder-type cycloadditions of aldehydes to dienes (Section D.l.6.1.1.1.2.4.). [Pg.96]
