AMINO ACID COMPOUNDS

摘要

This invention relates to amino-acid analogs, in particular to analogs which may be used in place of serine or threonine in the preparation of peptidic compounds. The analogs are compounds of formula (I) (where D is a bridging group which together with the carbon atom to which it is attached forms a substituted and/or saturated 4 to 10 membered carbocyclic ring) and stereoisomers, stereoisomer mixtures, salts, esters, amides and protected derivatives thereof.
