标题:Pyrrolylquinoxalinediones: A New Class Of Ampa Receptor Antagonists
摘要:Pyrrolylquinoxalinediones Were Synthesized And Their Affinities For The Ampa Receptor Were Determined. Most Compounds Showed Moderate To Good Affinities. The Acetic Acid Derivative 8B Exhibited A K-I Value Of 70 Nm And Was Equipotent To Nbqx 1. Structure Activity Relationships Are Discussed. Selected Compounds Were Tested For Their Potency To Inhibit Ampa Induced Lethal Convulsions In Mice. In This In Vivo Model The Compounds Showed Improved Potency Compared With Nbqx.

摘要:The present invention relates to the technical field of fine organic chemicals, and provides a continuous synthesis method for a disperse yellow dye. Continuous tubular reaction technology is used. A continuous tubular reactor provided by the present invention has a small volume, a large specific surface area, and a large heat transfer area per unit volume. The continuous tubular reactor can promptly transfer reaction heat by means of heat exchange and can ensure safety while accelerating the feeding speed. The continuous tubular reaction provided by the present invention precisely controls a raw material ratio, so that a feeding ratio of main raw materials is close to a theoretical value. In addition, by means of introducing an automatic control system, the chemical reaction can be carried out at a raw material ratio that strictly follows an optimal set value. The mass transfer and heat transfer effect of the continuous reactor is relatively good. Following the improvement to the mass transfer and heat transfer effect, the temperature control is more precise, and the generation of by-products is reduced.

标题 :Beta-chloroethylsulfonylmethyl-benzoic halides as intermediates
发明人：SCHLAEFER LUDWIG; HAEHNLE REINHARD
权利人:HOECHST AG
摘要:New beta -chloroethylsuflonylmethyl-benzoic acid halides which can serve as fibre-reactive anchors for thesynthesis of novel organic, water-soluble compounds, preferably dyestuffs, having fibre-reactive and fibre-finishing properties, such as preferably dyestuff properties, and containing, as a fibre-reactive group, one or two beta -chloroethylsufonylmethylbenzoic acid amide groups. For the synthesis of these novel fibre-finishing compounds, said new beta -chloroethylsulfonylmethyl-benzoic acid halide compounds are reacted with an organic, water-soluble compound having fibre-finishing properties and continuing one or two amino groups. Also precursors of the fibre-finishing, fibre-reactive compounds, containing said beta -chloroethylsulfonylmethyl-benzxoic acid amid grouping, can be employed for their synthesis. The novel fibre-finishing compounds can be applied onto suitable fibre materials, such as especially cellulose fibre material and natural or synthetic polyamide fibre materials, and fixed on these fibre materials in a manner similar to application and fixation methods usual in the technique for fibre-reactive compounds. The fibre-finished material, such as dyed material, shows very good wet fastnesses.
