Oxalysine-L, L-4-Oxalysine, I-677
O-(2-氨基乙基)-L-丝氨酸 L-4-噁溶菌素盐酸盐 Chemical Name: L-4-Oxalysine; O-(2-Aminoethyl)-L-serine
CAS No. 15219-97-3, 118021-35-5 (monoHCl), 997-44-4 (undefined stereoch.)
项目整合开发状态: Phase II
项目研究机构: Shanghai Institute Materia Medica (Originator)
合成路线:The interaction of 2-chloroethyl chloromethyl ether (I) and the sodium salt of 2-phthalimidomalonate (II) in dimethylformamide afforded the condensation product (III).An amino group was then introduced to the latter compound by means of potassium phthalimide (A),giving (IV).The racemic amino acid (V) could be obtained on removal of the phthalyl groups by treatment with hydrazine.However,the racemic phthalimide compound (IV) could be used directly for resolution through the brucine salt,and the protecting groups were then removed by hydrolysis with 6N hydrochloric acid.The levo-amino acid (V) was finally isolated as the dihydrochloride.
