An efficient methodology for the synthesis of isoindolo[1,2-a]isoquinolones based on two Parham-type cyclizations allowing the formation of the five- and six-membered nitrogenated rings from carbamate or diacylamine precursors is described. The synthetic potential of this method has been further illustrated by the total synthesis of the alkaloid nuevamine. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451
描述了一种合成异吲哚并 [1,2-a] 异喹诺酮类的有效方法,该方法基于两个 Parham 型环化,允许从氨基甲酸酯或二酰胺前体形成五元和六元氮化环。生物碱 nuevamine 的全合成进一步说明了该方法的合成潜力。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
