The invention relates to new (4S)-4-aminobutanoic acid derivatives of general formula: ##STR1## in which: R represents an N-protective group, R.sub.1 represents hydrogen, an alkali metal atom such as lithium, sodium or potassium or a liabile group, R.sub.2 represents a group of formula: ##STR2## in which W represents hydrogen, a hydroxy group or an alkyl radical containing from 1 to 4 carbon atoms or an alkoxy radical containing from 1 to 4 carbon atoms, and to a process for the preparation of the said derivatives. The 4-aminobutanoic acid derivatives according to the invention are useful as synthesis intermediates for the preparation of peptides derived from statin analogues.
本发明涉及新的(4S)-4-氨基丁酸衍生物,通式如下:##STR1##
其中:R代表N保护基,R.sub.1代表氢,碱金属原子如锂、钠或钾或可溶性基团,R.sub.2代表下列公式的基团:##STR2##
其中W代表氢、羟基或含有1至4个碳原子的烷基基团或含有1至4个碳原子的烷氧基基团,并且本发明还涉及制备所述衍生物的方法。根据本发明的4-氨基丁酸衍生物可用作合成类似于他汀的肽衍生物的中间体。
