摘要:
Described are aminophenol derivatives of general formula (I) in which one of the two groups R and R is hydrogen and the other is hydrogen, chlorine or fluorine; one of the two groups R and R is hydrogen, a C1-4-alkoxy group, a C1-4-alkyl group, a C1-4-hydroxyalkyl group, preferably with a terminal hydroxy group or halogen and the other is one of the groups: -O-CH2-CH=CH2, -CH=CH-COOX in which X is hydrogen or a physiologically tolerable inorganic or organic cation and, in the case when the group concerned is R , the group (a) and, in the case when the group concerned is R , (b), in which -A- in each case is one of the groups -(CH2)x- in which x = 1 to 4, -O-(CH2)y-O- in which y = 1 to 4, -O-(CnH2n-z(OH)z)-O- in which n = 1 to 10 and z = 1 or, when n is greater than or equal to 3, z = 2, -O-(C2H4-O)u- in which u = 1 to 4 and -O-(C3H6-O)v- in which v is 1 to 4. Such derivatives are particularly suitable for use as developers in oxidative dyes for dyeing keratin fibres. Brilliant hues with a high degree of fastness are obtained with the usual coupling agents, particularly when dyeing hair.

Light activated acyl-enzymes of formula (III) are disclosed. In the compounds of formula (III) ENZ is an enzyme, X is O or S, Y is -NR3R4, -OR5, or -SR5, and Z is a nucleophile; m is 0 to 3 and n is 1 or 2; Y is substituted on the ring at either or both of the 4 and 6 position. R1 and R2 are each independently H, C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl. R3 and R4 are each independently H, C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl, except that R3 and R4 are not simultaneously both H. R5 is C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl. Methods of using the acyl-enzymes and intermediates for making the acyl-enzymes are disclosed. A preferred intermediate is 2-propenoic acid, 3-(2-hydroxy-4-diethylaminophenyl)-2-methyl-, 4-(aminoiminomethyl)phenyl ester, (E)-, monohydrochloride salt, which is preferably reacted with thrombin to form an acyl-thrombin.
