  Preparation of both enantiomers of 1-allyl-1,2,3,4-tetrahydro-β-carboline using allyltin reagents and a chiral auxiliary derived from l-proline

  摘要：

  beta -Carboline, which had an acyl group derived from L-proline at the 9-position, reacted with allyltributyltin and 2,2,2-trichloroethyl chloroformate, to afford an 1-allyl-1,2-dihydro-beta -carboline derivative in a diastereo selective manner. The chiral acyl group at N-9 was readily eliminated by aqueous alkali to give a corresponding carboxylic acid. The formed 1-allyl-1,2-dihydro-beta -carboline was transformed via two reduction steps to 1-alkyl-1,2,3,4-tetrahydro-beta -carboline in high ee. When the allylation was carried out using tetraallyltin instead of allyltributyltin, the stereoselectivity was reversed, and the antipode of the allyl adduct was obtained in high yield and ee in the presence of tin(IV) tetraiodide. Thus, it was found that both enantiomers of 1-allyl-beta -carboline were obtained in good enantioselectivities by the use of the same chiral auxiliary. (C) 2001 Elsevier Science Ltd.

  β-Carboline was acylated at its 9-position by a chiral acyl chloride, followed by reaction with allyltributyltin and 2,2,2-trichloroethyl chloroformate to afford an 1-allyl-1,2-dihydrocarboline derivative in a diasteroselective manner. The chiral acyl group at N-9 was readily eliminated by aqueous alkali to give carboxylic acid quantitatively without racemization on C-1 position. The formed 1-allyl-1,2-dihydro-β-carboline was transformed to 1-allyl-1,2,3,4-tetrahydro-β-carboline.

  β-咔啉在其9-位被手性酰氯酰化，然后与烯丙基三丁基锡和2,2,2-三氯乙基氯甲酸酯反应以非对映选择性方式提供1-烯丙基-1,2-二氢咔啉衍生物。 N-9位上的手性酰基很容易被碱水溶液消除，定量地得到羧酸，而C-1位上没有外消旋化。形成的1-烯丙基-1,2-二氢-β-咔啉转化为1-烯丙基-1,2,3,4-四氢-β-咔啉。
