the synthesis and NMR characterization of four mono- and four dideoxygenated analogs of α,α- d -trehalose. The symmetrical (2,2′-, 3,3′-, 4,4′- and 6,6′-) dideoxy analogs were obtained via selective protection and subsequent radical deoxygenation of the desired hydroxyl group set. The unsymmetrical (2′-, 3′-, 4′- and 6′-) monodeoxy analogs were synthesized by desymmetrization of α,α-trehalose and subsequent
摘要在本文中,我们描述了α,α-d-海藻糖的四个单脱氧和四个双脱氧类似物的合成和NMR表征。对称的(2,2'-,3,3'-,4,4'-和6,6'-)双脱氧类似物是通过选择性保护和随后的所需羟基组的自由基脱氧而获得的。通过α,α-海藻糖的脱对称和随后在自由基条件下的脱氧合成不对称的(2'-,3'-,4'-和6'-)单脱氧类似物。通过广泛使用2D 1 H,1 H}和1 H,13 C}相关NMR实验,可以实现这些脱氧海藻糖光谱中所有1 H和13 C共振的完全分配。
