When the series of 2-, 3-, and 4-(benzylamino)-2-, 3-, and 4-deoxy derivatives of 1,6-anhydro-beta-D-hexopyranoses in the D-gluco, D-lyxo, and D-arabino configurations were reacted with diisopropyl azodicarboxylate, N-benzyl groups were selectively cleaved in the presence of O-benzyl groups. The yields ranged from 51 to 97%. The debenzylation of some aliphatic benzylamines is also discussed.
当D-葡萄糖,D-lyxo中的1,6-脱水β-D-六吡喃糖的2-,3-和4-(苄氨基)-2-,3-和4-脱氧衍生物系列时,使D-阿拉伯糖构型与偶氮二羧酸二异丙酯反应,在O-苄基存在下选择性地裂解N-苄基。产率为51%至97%。还讨论了一些脂族苄胺的脱苄基作用。
