A method for the synthesis of 5-aryl-1,3,3,-trimethyl-2-methylene-indoline derivatives of Formula (I) or its salts of Formula (Ia)
1
wherein 1 mole of a 5-aryl-2,3,3-trimethyl-3H-indole derivative of Formula (VII) is reacted for 1 to 44 hours at a temperature of 20° to 180° C. in an apolar, aprotic or polar, protic or polar aprotic solvent with 1 to 50 moles of a compound of Formula R1-A; new compounds of Formulas (I)/(Ia) and (V), obtainable by this method
2
as well as an agent containing at least one compound of Formula (I)/(Ia) and a carbonyl/inune compound for dyeing keratinic fibers and a method for temporarily dyeing keratin fibers, for which the keratin fiber is dyed with the aforementioned agent and the dyeing, so obtained, is removed again at any later time by a sulfite preparation.
Polymerisation of vinyl chloride in aqueous suspension using a polymerisation reactor having adherently deposited on internal surfaces thereof a build-up suppressant coating comprising a product of build-up suppressant activity formable by (and preferably formed by) the condensation of an effective 1-naphthol (preferably 1-naphthol itself) and formaldehyde. The condensation is preferably effected in a base-catalysed reaction; it may also (less preferably) be effected in an acid-catalysed reaction. The coating product ° itself and a process for its production are also claimed.
The present invention relates to an agent for dyeing keratin fibers, containing at least one compound with a nucleophilic reaction center, at least one alcohol from the group comprising aryl alcohol derivatives and benzyl alcohol derivatives and at least one suitable oxidizing enzyme, as well as to a method for dyeing keratin fibers using this agent.
The present invention relates to combinations of xylose compounds with other pharmaceutically active compounds, to pharmaceutical compositions comprising said combinations, as well as to use of these combinations for the manufacture of a medicament for treatment of proliferative disorders. In another aspect, the present invention relates to novel xylose compounds, to pharmaceutical compositions comprising said compounds, and to use of these compounds for the manufacture of a medicament or the treatment of proliferative disorders.
