标题 :Highly enantiomerically pure lactam-substituted propanoic acid derivatives and methods of making and using same

摘要:The present invention relates to highly enantiomerically pure lactam-substituted propanoic acid derivatives and methods of making and using therefor. The invention involves a multi-step synthesis to produce the lactam compounds. In one step of the reaction sequence, asymmetric hydrogenation of a lactam-enamide was performed to produce an intermediate that can ultimately be converted to a series of pharmaceutical compounds. The invention also contemplates the in situ synthesis of an intermediate of the multi-step synthesis, which provides economic advantages to the overall synthesis of the lactam compounds.

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.
