Due to significant activity profile and natural abundance of β‐carboline containing alkaloids, β‐carboline N‐fused imidazole derivatives were designed and iodine assisted efficient approach was formulated for the regioselective synthesis of designed prototypes via decarboxylative amination of natural α‐amino acids with 1‐formyl pyrido[3,4‐b]indoles. Additionally, oxidative amination with benzyl amines
由于具有明显活性的生物碱和自然丰富的含β-咔啉的生物碱,因此设计了β-咔啉N融合的咪唑衍生物,并制定了碘辅助有效方法,通过天然α-氨基酸的脱羧胺化(1)来设计原型的区域选择性合成。-甲酰基吡啶基[3,4- b ]吲哚。此外,还研究了苄基胺的氧化胺化反应,以合成这些含β-咔啉D-环的骨架。
