α-Amino γ-lactams have been synthesized from carbohydrate derived cyclopropanecarboxylates using N-iodosuccinimide (NIS) and NaN3. Cyclopropane ring opening with NIS and NaN3 in different solvents has been studied. Reductive cyclization of the intermediate di-azides leads to the carbohydrate fused α-amino γ-lactam and γ-lactams. Additionally, the methodology has been successfully extended to the synthesis of a glycopeptide.
已使用N-碘代琥珀酰亚胺(NIS)和叠氮化钠从碳水化合物衍生的环丙烷羧酸盐合成了α-氨基γ-内酰胺。研究了在不同溶剂中用NIS和叠氮化钠使环丙烷开环的反应。中间体二叠氮化物的还原环化反应生成了碳水化合物稠合的α-氨基γ-内酰胺和γ-内酰胺。此外,该方法已成功扩展至糖肽的合成。
