In order to obtain various bis-amino acids, we have firstly synthesized
protected amino acids functionalized with azido or alkyne
functions. O-Propargyl Boc-Ser-OMe 11,8 3-azido Boc-Ala-OMe 12,9
3-azido Boc-Ala-OBn 13,10 O-propargyl Boc-Tyr-OMe 1411 have
been prepared according to the literature procedure. O-Propargyl
Boc-Ser-OBn 15 was obtained from Boc-Ser-OH by O-alkylation and
esterification reactions (Scheme 1). By a diazotransfer reaction with
imidazole-1-sulfonyl azide,12 Na-Cbz-Lys-OH has been transformed
into the corresponding azide 16 in 70% yield after esterification
with SOCl2 and MeOH.

为了提取多种双氨基酸,我们首先将氨基酸与叠氮基或炔特性的化合物合成.根据资料提供的步骤,O-Propargyl Boc-Ser-OMe 11,8 3-azido Boc-Ala-OMe 12,93-azido Boc-Ala-OBn 13,10 O-propargyl Boc-Tyr-OMe 1411 【抱歉俺翻不出化合物】已准备好.O-Propargyl Boc-Ser-OBn 15 是经过O-烷基化和酯化反应从Boc-Ser-OH提取出来的(见方案1).12 Na-Cbz-Lys-OH 与imidazole-1-sulfonyl azide重氮化反应之后与氧氯化硫和甲醇产生酯化反应,其70%已经转化为corresponding azide 16 .
