Abstract A series of chiral morpholino [4, 3-a] benzimidazole derivatives were synthesized effectively from (S)-(-)-2-(α-hydroxyethyl)-benzimidazole and phenacyl bromide derivatives using an efficient synthetic protocol in good yields and moderate diastereoselectivities. The substrate controlled diastereoselective route makes available structurally attractive morpholine-fused benzimidazole derivatives
摘要 使用高效的合成方案,从 (S)-(-)-2-(α-羟乙基)-苯并咪唑和苯甲酰溴衍生物有效合成了一系列手性吗啉 [4, 3-a] 苯并咪唑衍生物非对映选择性。底物控制的非对映选择性路线使结构上有吸引力的吗啉稠合苯并咪唑衍生物以对映体富集形式具有两个手性中心。初步生物学评估显示了潜在应用的范围。图形概要
