标 题:Synthesis of phenoxyanthraquinones

权利人:TOMS RIVER CHEMICAL CORP
摘要:A method of synthesizing phenoxyanthraquinones in the absence of excess phenol, water-miscible alcohols or polar aprotic solvents. Phenoxyanthraquinones are synthesized in high yield and purity by treatment of the corresponding chloro- or nitroanthraquinone with an equivalent of alkali metal phenoxide, particularly potassium phenoxide in a liquid aromatic solvent which is a chloro-substituted benzene, a lower alkyl-substituted benzene, or a loweralkyl-chloro-substituted benzene. The use of the inventive solvents results in high yields of readily isolable, substantially pure product. The used solvent is readily recoverable without the pollution potential of excess phenol or difficultly recoverable water-miscible solvents.

According to the practice of the invention, there are provided bis-symmetrical substituted anthraquinone compounds according to formula I: n n nwherein R1, R2, R3 and R4 present a straight, aminoalkylamino side chains or branched chain alkyl group having 1 to 6 carbons which may be substituted with one or more groups of R5, or R1, R2, R3 and R4 present phenyl or benzyl which may be substituted with one or two groups of R6; wherein R5 is selected from the group consisting of halogen, —RNH 2 , —RNH 2 R, —ROH, —NO 2 , —OCH 3 , —OCH 2 CH 3 , and —OCH 2 CH 2 CH 3 ; and wherein R6 is selected from the group consisting of a straight or branched chain alkyl group having 1 to 4 carbons, halogen, —RNH 2 , —RNH 2 R, —ROH, —NO 2 , —OCH 3 , —OCH 2 CH 3 , —OCH 2 CH 2 CH 3 , —CH 2 Br, —CH 2 Cl, —CH 2 OH, —C(CH 3 ) 3 , —(CH 2 ) 2 0H, —(CH 2 ) 3 OH, —(CH 2 ) 4 OH, —CH 2 NH 2 , —(CH 2 ) 2 NH 2 , —(CH 2 ) 3 NH 2 , —(CH 2 ) 4 NH 2 , —(CH 2 ) 5 NH 2 , —CH 2 N(CH 3 ) 2 , —(CH 2 ) 2 N(CH 3 ) 2 , —(CH 2 ) 2 NH(CH 2 ) 2 OH, —(CH 2 ) 3 NH(CH 2 ) 2 OH, —(CH 2 ) 2 NHCH 2 OH, —(CH 2 ) 3 NHCH 2 OH, —CH 2 CH(CH 3 ) 2 , —CHCl 2 , —CH(CH 3 )Cl, —(CH 2 ) 2 Cl, —(CH 2 ) 3 Cl, —(CH 2 ) 3 Br, —(CH 2 ) 4 Br, and —(CH 2 ) 4 Cl. n n Chart 1. Activation of hTERT promoter-driven SEAP expression by c-Myc. About 1×10 7 hTERT-BJ1 cells were transfected with 13.5 μg each of plasmid pSEAP or pPhTERT-SEAP and of plasmid pMT2T or pMT2T-cMyc by electroporation. After 24 h, viable cells were harvested, and reinoculated at a density of 3×10 5 /mL, and the SEAP activity after 24 h at 37 â–¡. The transfection efficiency of each experiment was determined by cotransfection with 1.5 μg of plasmid pCMVβ. The values were determined from three experiments. P<0.05 is presented by an asterisk.

标题:Anthraquinone dyestuffs

摘要:The invention relates to a process for the preparation of water-insoluble chlorine-containing diaminodihydroxyanthraquinone dyestuffs. The process consists in that 2,8-dichloro-1,5-dinitroanthraquinone and/or 2,5-dichloro-1,8-dinitroanthraquinone is warmed with sulphur in concentrated sulphuric acid having a maximum SO 3 content of 20% - possibly in the presence of boric acid - the resulting compounds are, if appropriate, post-halogenated and/or alkylated, preferably in the same reaction batch. n The main advantage of this process is that it starts from 1,6- and/or 1,7-dichloroanthraquinone, for which there was hitherto no industrial use, but which unavoidably also arise during the synthesis 1,5- and 1,8-dichloroanthraquinones.
