treated with N-benzyloxycarbonyl or N-fluorenylmethoxycarbonyl protected aminohexanols (used as the spacer arm), unusual stereoselectivities were observed for the synthesis of the alpha and beta anomers. The synthesis of the alpha anomer could only be achieved, in reasonable yields, with the Schiff base of aminohexanol.
T抗原[β-D-Gal-(1-> 3)-D-Ga1NAc]已通过C6间隔臂与生物素连接,用于检测表面的特定“ T-抗原-凝集素”复合物和/或黑色素瘤细胞的迁移途径。当4,6-二-O-乙酰基-2-叠氮基-2-脱氧-3-O-(2,3,4,6-四-O-乙酰基-β-D-吡喃半乳糖基)-α-或-β用N-苄氧基羰基或N-芴基甲氧基羰基保护的氨基己醇(用作间隔臂)处理-D-吡喃半乳糖基卤化物,观察到异常的立体选择性,用于合成α和β异构体。只有使用氨基己醇的席夫碱才能以合理的收率完成α端基异构体的合成。
