The reaction of tryptamine with α-ketoesters in the presence of a catalytic amount of a chiral alanine-derived squaramide and 4-nitrobenzoic acid afforded the corresponding 1-alkyl-1-methoxycarbonyl tetrahydro-β-carbolines (THBCs) in high yields and ee values. A concise seven-step asymmetric total synthesis of alstratine A, a cagelike hexacyclic indole alkaloid, was developed featuring this enantioselective
在催化量的手性丙氨酸衍生角酰胺和 4-硝基苯甲酸存在下,色胺与 α-酮酯反应得到相应的 1-烷基-1-甲氧基羰基四氢-β-咔啉 (THBC),产率和ee值。笼状六环吲哚生物碱 alstratine A 的简明七步不对称全合成以这种对映选择性 Pictet-Spengler 反应为关键步骤。

Studies on Neurokinin Antagonists. 4. Synthesis and Structure-Activity Relationships of Novel Dipeptide Substance P Antagonists: N2-[(4R)-4-Hydroxy-1-[(1-methyl-1H-indol-3-yl)carbonyl]-L-prolyl]-N-methyl-N-(phenylmethyl)-3-(2-naphthyl)-L-alaninamide and Its Related Compounds
As an extension of our studies on discovering a novel substance P (SP) antagonist, we modified the previously reported dipeptide, N-2-[N-2-(1H-indol-3-ylcarbonyl)-L-lysyl]-N-methyl-N-(phenylmethyl)-L-phenylalaninamide (2b). The lysine part in 2b was first optimized to a (2S,4R)hydroxyproline derivative (3h),which is 2-fold more potent than 2b in [H-3]SP binding assay using guinea pig lung membranes. Next we modified the 1H-indol-3-ylcarbonyl part in 3h. Introduction; of a methyl group at the indole nitrogen enhanced the oral activity, while retaining the binding activity. Finally, we modified the phenylalanine part to culminate in the most potent compound 7k (FK888), which is a potent SP antagonist with NK1 selectivity as well as oral activity.
