Abstract Derivatives of methyl 2-amino-2-deoxy-α- d -altropyranoside- 2 - 15 N and methyl 3-amino-3-deoxy-α- d -glucopyranoside- 3 - 15 N have been synthesized by addition of phthalimide- 15 N to methyl 2,3-anhydro-4,6- O -benzylidene-α- d -allopyranoside. The structures of the phthalimido derivatives that resulted have been proved chemically, by conversion into known aminodeoxy derivatives, and spectroscopically
摘要通过邻苯二甲酰亚胺-邻苯二甲酰亚胺合成了2-氨基-2-脱氧-α-d-羟吡喃糖苷-2-15 N和甲基3-氨基-3-脱氧-α-d-吡喃葡糖苷-3-15N的衍生物。 15 N为甲基2,3-脱水-4,6-O-亚苄基-α-d-吡喃吡喃糖苷。所得邻苯二甲酰亚胺基衍生物的结构已通过化学转化为已知的氨基脱氧衍生物进行了证明,并通过1 H-和13 Cn.mr光谱进行了光谱分析。1 HN.mr光谱在360 MHz下也可以定义标记的和未标记的邻苯二甲酰亚胺基衍生物的构型和构象,并测量具有1 H-15 N二面角的邻位1 H-15 N偶合常数。 60°。
