专利号:US-7576234-B2 优先权日:2002-05-15 标题 :Synthesis of 2-alkyl amino acids 发明人:CHORGHADE MUKUND S; GURJAR MUKUND K; MOHAPATRA DEBENDRA K 权利人:GENZYME CORP 摘要:Non-natural amino acids such as 2-alkylated amino acids allow for the synthesis of a wider variety of peptidal and non-peptidal pharmaceutically active agents. A method of preparing a 2-alkyl amino acid involves a Michael-type addition of a nucleophile to a dialkyl 2-methylidenylpropan-1,3-dioate and the conversion of a ester moiety into an amino moiety. The present invention also discloses a method of preparing a class of iron chelating agents related to desferrithiocin, all of which contain a thiazoline ring. In this method, an aryl nitrile or imidate is condensed with cysteine, a 2-alkyl cysteine, or a cysteine ester.

The compounds of the invention have the formula: where R1 to R4 are hydrogen or lower alkyl (C1 to C5), provided that the compound has no more than 18 carbon atoms. The invention provides for synthesis of a novel phenolic intermediate and synthesis of the compounds of the invention. The invention also provides fragrance compositions which utilize the compounds of the invention to modify, enhance, or impart a musk-like aroma to perfume compositions, colognes and perfumed articles.
