Tilivalline(1a),肺炎克雷伯菌的一种代谢产物。催产素及其衍生物1已由叠氮基磷酸二苯酯,2-恶唑啉2,L-脯氨酸衍生物5和吲哚有效地和立体选择性地合成;关键步骤是伴随完全立体选择性引入吲哚的曼尼希型分子内环化反应。此外,通过使用这种新的曼尼希型环化反应,还由乙缩醛酰胺9a和各种亲核试剂合成了11个取代的5 H-吡咯并[2,1- c ] [1,4]苯并二氮杂-5-酮(16)。。
Tilivalline (1), a metabolite from Klebsiella, has been efficiently and stereoselectively synthesized from diphenyl phosphorazidate (DPPA), the 2-oxazoline 2, the L-proline derivative 5, and indole: the key step is a Mannich type intramolecular cyclization accompanied with simultaneous and completely stereoselective introduction of indole.
