This invention pertains to amino acids attached to a solid support in a racemization free manner and to a method of covalently linking amino acids to solid supports for use in solid phase peptide syntheses, through
a compound of the formula: wherein Z is an Nα protecting group;
B is one or more amino acids having protected or unprotected side chains;
R₁ and R₂ are the same or different and are selected from the group consisting of hydrogen, a linear or branched, saturated or unsaturated alkyl, aryl and benzyl;
A is a substituted or unsubstituted aromatic ring;
Y is a hydrocarbon chain having a linear or branched, saturated or unsaturated alkyl, aryl or aralkyl which may be linked to A through an ether linkage;
D is an oxygen or -NH- which may be linked to a spacer selected from the group consisting of one or more natural and unnatural amino acids or hydrocarbon chain having a linear or branched, saturated or unsaturated alkyl, aryl or aralkyl group, the spacer being linked to the carbonyl through an oxygen or -NH- linkage; and
SS is a solid support which is bound to the carbonyl group through D.
本发明涉及以无消旋化方式连接到固体支持物上的氨基酸,以及将氨基酸共价连接到固体支持物上以用于固相肽合成的方法,其通过
式中 Z 为 Nα 保护基团的化合物;
B 是一个或多个具有受保护或不受保护侧链的氨基酸;
R₁ 和 R₂ 相同或不同,选自由氢、直链或支链、饱和或不饱和烷基、芳基和苄基组成的组;
A 是取代或未取代的芳香环;
Y 是具有线性或支链、饱和或不饱和烷基、芳基或芳烷基的烃链,可通过醚键与 A 连接;
D 是氧或-NH-,可与选自一个或多个天然和非天然氨基酸或具有线性或支链、饱和或不饱和烷基、芳基或芳烷基的烃链的间隔物连接,间隔物通过氧或-NH-连接与羰基连接;以及
SS 是固体支持物,通过 D 与羰基结合。
