  摘要：

  合成了两种四氢-β-咔啉-1和-4-羧酸（1b，c）及相应的羟甲基衍生物（2b，c），它们是3-羧酸（1a）及其3-羟甲基衍生物（2a）的位置异构体，并测试了它们对四氯化碳（CCl4）诱导的小鼠肝损伤的保肝活性。这些位置异构体的保肝活性依次降低：1a>1b>1c>和2a>2b>2c。顺式和反式异构体（5a、b-14a、b）也检测了 1a 和 2a 1 位上烷基取代的影响。带有小烷基（如 Me 和 Et）的化合物显示出强大的活性。烷基加长一般会导致活性降低。在一系列 3-羧酸立体异构体（5a、b-9a、b）中，顺式异构体的活性往往高于反式异构体。

  Highly stereoselective transformation of (1S,3S)-cis-1,3-disubstituted tetrahydro-β-carbolines into (1S,3R)-trans-1,3-disubstituted tetrahydro-β-carbolines: an improved asymmetric synthesis of tadalafil from l-tryptophan

  摘要：

  An efficient and general method for the highly stereoselective transformation of (1S,3S)-cis-1,3-disubstituted 1,2,3,4-tetrahydro-beta-carbolines (THBCs) into (15,3R)-trans-1,3-disubstituted THBCs is described. The method contains the following three steps: the enantiomerically pure (1S,3S)-cis-1,3-disubstituted THBCs 1 were first converted into (1S,3S)-cis-1,2,3-trisubstituted THBCs 2 by N-1-naphthylmethylation/benzylation; (15,3S)-cis-1,2,3-trisubstituted THBCs 2 were then converted into (1S,3R)-trans-1,2,3-trisubstituted THBCs 3 in high yields and with high stereoselectivities via a base-catalyzed epimerization at C-3; (1S,3R)-trans-1,2,3-trisubstituted THBCs 3 were subsequently converted into (15,3R)-trans-1,3-disubstituted THBCs 4 after reductive removal of the 1-naphthylmethyl/benzyl group. In addition, as an application of this method, an improved and highly stereoselective synthesis of the PDE5 inhibitor tadalafil (Cialis (R)) starting from natural and less expensive L-tryptophan was developed.

  An efficient and general method for the highly stereoselective transformation of (1S,3S)-cis-1,3-disubstituted 1,2,3,4-tetrahydro-beta-carbolines (THBCs) into (15,3R)-trans-1,3-disubstituted THBCs is described.

  Two tetrahydro-β-carboline-1-and-4-carboxylic acids (1b, c) and the corresponding hydroxymethyl derivatives (2b, c), which are positional isomers of the 3-carboxylic acid (1a) and its 3-hydroxymethyl derivative (2a), were synthesized and tested for hepatoprotective activity against carbon tetrachloride (CCl4) -induced liver damage in mice. The hepatoprotective activity of these positional isomers decreased in the following order;1a> 1b> 1c> and 2a > 2b>2c. The effect of alkyl substitution at the 1 position of 1a and 2a was also examined with the cis and trans isomers (5a, b-14a, b). Compounds with small alkyl groups such as Me and Et showed potent activity. Lengthening of the alkyl group generally caused a decrease in activity. In a series of the stereoisomers of the 3-carboxylic acids (5a, b-9a, b), the cis isomers tend to be more active than the trans counterparts.
