trehalosamine, α-D-galactopyranosyl 2-amino-2-deoxy-α-D-glucopyranoside, was synthesized by the glycosylation of 2,3,4,6-tetra-O-(p-chlorobenzyl)-α-D-galactopyranose with 3,4,6-tri-O-acetyl-2-deoxy-2-(2,4-dinitroanilino)-α-D-glucopyranosyl bromide, using silver perchlorate and tribenzylamine in benzene, followed by chromatographic separation and the subsequent removal of the protecting groups. Similarly, α-D-mannopyranosyl
海藻胺的新类似物α-D-吡喃半乳糖基2-氨基-2-脱氧-α-D-吡喃葡萄糖苷通过2,3,4,6-四-O-(对氯苄基)-α的糖基化合成-D-吡喃半乳糖与 3,4,6-tri-O-acetyl-2-deoxy-2-(2,4-dinitroanilinino)-α-D-glupyranosyl bromide,在苯中使用高氯酸银和三苄胺,然后进行色谱分离以及随后去除保护基团。类似地,合成了α-D-吡喃甘露糖基2-氨基-2-脱氧-α-D-吡喃葡萄糖苷。这些 α,α-二糖的糖苷键的构象与它们异头碳的 13C 化学位移有关。
