modified Strecker reaction of N-Boc protected amino aldehydes and methyl anthranilate, reduction of the resulting α-amino nitriles, and lactamization. The resulting 2-substituted-5-oxo-1,2,3,4-tetrahydro-5H-1,4-benzodiazepines were further functionalized at position 4 by alkylation or acylation reactions. One of these new tryptophan-derived 1,4-benzodiazepines showed significant selective binding affinity
描述了苯丙氨酸和色氨酸衍生的5-氧代-1,2,3,4-四氢-5 H -1,4-苯并二氮杂衍生物的立体控制合成。这种新方法涉及N- Boc保护的氨基醛和邻氨基苯甲酸甲酯的改良Strecker反应,还原所得的α-氨基腈和内酰胺化。通过烷基化或酰化反应,将得到的2-取代的5-氧代-1,2,3,4-四氢-5 H -1,4-苯并二氮杂在4位进一步官能化。这些新的色氨酸衍生的1,4-苯并二氮杂之一在胆囊收缩素CCK 1受体上表现出显着的选择性结合亲和力(IC 50 = 156.5±33.2 nM)。
