  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。

  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.

  Stereoelectronic control in the Pictet-Spengler condensation of N(b)-alkylsubstituted tryptophan alkyl esters has been employed to promote 100% stereoselectivity in this process. The reaction of N(b)-diphenylmethyl tryptophan isopropyl ester 8 with acetaldehyde in benzene at reflux yielded the trans-diastereomer 10d to the complete exclusion of the corresponding cis isomer. This trans stereospecificity was also observed for butyraldehyde and cyclohexylcarboxaldehyde.

Conversion of the cis diastereomers into the more stable trans diastereomers is believed to occur under acidic conditions by cleavage of the carbon (C-1)-nitrogen (N-2) bond with complete retention of configuration at the C-3 stereocenter. Evidence from deuterium exchange experiments as well as optical rotations support this model for epimerization. In addition, when cis diastereomer

  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.
