英语翻译
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.
