amination of Fmoc-amino aldehydes by NaBH3CN are described. From glycine and Fmoc-4-t-Butoxy-tyrosinal, a small amount of double condensation product was obtained beside the initially desired product Fmoc-Tyr(OtBu)-ψ(CH2NH)-Gly-OH. From glycine methyl ester and Fmoc-glycinal, we only recovered the reduced peptide bond isostere, but from glycine and Fmoc-glycinal, bis(Fmoc-amino ethyl)-N-glycine was obtained
描述了NaBH 3 CN还原Fmoc-氨基醛的意外结果。除了最初需要的产物Fmoc-Tyr(OtBu)-ψ(CH 2 NH)-Gly-OH,还从甘氨酸和Fmoc-4-t-丁氧基-酪氨酸中获得了少量的双缩合产物。从甘氨酸甲酯和Fmoc-甘氨酸,我们仅回收了还原的肽键等排体,但是从甘氨酸和Fmoc-甘氨酸,获得了双(Fmoc-氨基乙基)-N-甘氨酸作为主要产物。
