标 题:Solid-phase synthesis of N-alkyl amides
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.

摘要:The present invention relates to the synthesis of 2,2-dimethyl-3-(vinyl-2,2-bi-substituted) cyclopropanocarboxylic acids. Said acids are present in the majority of natural pyrethrines and in synthetic pyrethroids. These acids are obtained by the transposition reaction aza-di-Ï€-methane of a 1-aza-1,4,6-trianic system for which there are disclosed three different synthetic processes. Thereby, precursors are available to obtain pyrethrines and pyrethroids, obtained by a direct and simple process with a high yield.

摘要:This invention provides a purified chrysanthemyl diphosphate synthase (CDS), a method for the purification of CDS from Chrysanthemum cinerariaefolium, and an amino acid sequence of the isolated CDS. Also provided is a cDNA encoding the CDS, a nucleotide sequence of the CDS gene, and a derived amino acid sequence of the encoded CDS protein. The CDS gene is useful in the enzymatic production of the natural stereospecific configuration of chrysanthemyl derivatives which are useful for the synthesis of pyrethrins, pyrethroids, derivatives thereof, as well as other classes of metabolites.

发明人：NEVALAINEN VESA; SYLVESTRE DEGNI
权利人:NESTE CHEMICALS OY; NEVALAINEN VESA; SYLVESTRE DEGNI
摘要:The invention relates to chiral amino alcohol derivatives of pyridine, which compounds are useful as catalysts in combination with organic zinc compounds for asymmetric induction reactions and more particularly for enantioselective synthesis of optically active alcohols from aldehydes. The invention also relates to a process for the preparation of the said amino alcohol derivatives of pyridine and to a method for the manufacture of optically active alcohols from aldehydes in the presence of organic zinc compounds and amino alcohol derivatives of pyridine.
