发明人：BROWN EDWARD G; NUSS JOHN M
权利人:CHIRON CORP
摘要:Methods for solid phase synthesis of N-alkyl amides comprise reductive amination of carbonyl compounds using a reducing agent and an amine-containing linker bound to a solid support. The methods afford high yields of linker-bound, monoalkylated amines, and subsequent coupling with acid derivatives provide derivatized N-substituted amides in excellent yields after cleavage from the solid-phase. Compositions useful in solid phase synthesis are also described.

标题:Process and reagent useful for the synthesis of sulphanilide which is perhalogenated on the carbon borne by the sulphur atom of the sulphanilide function

摘要:The present invention relates to a process and a reagent useful for the synthesis of sulphanilide which is perhalogenated on the carbon borne by the sulphur atom of the sulphanilide function. This persulphonylation process is characterized in that it comprises a step of placing a nucleophile, whose nucleophilic atom is a nitrogen, in contact with a reagent comprising, for successive or simultaneous addition, a heavy halide of sulphonyl, advantageously sulphonyl chloride, and an organic base comprising a trivalent atom from column V whose lone pair is conjugated directly or indirectly to a bond, and in that the organic part of the said sulphonyl is perhalogenated, advantageously perfluorinated, on the carbon borne by the sulphur. Application to the synthesis of intermediates for organic chemistry.
