and few efficient treatments are available. Recently, the two benzochromenes pulchrol (1) and pulchral (2) were reported from the roots of Bourreria pulchra, and especially 1 but also 2 was found to be active towards the parasites. In this paper, we present a total synthesis of 1 and 2 to facilitate their biological evaluation. The synthesis is mild, short, and high yielding and suitable for a structure-activity
寄生虫 Leshmania mexicana 和 Trypanosoma cruzi 会导致严重的健康问题,并且几乎没有有效的治疗方法。最近,从 Bourreria pulchra 的根中报道了两种苯并色烯 pulchrol (1) 和 pulchral (2),特别是 1 和 2 被发现对寄生虫有活性。在本文中,我们提出了 1 和 2 的全合成,以促进它们的生物学评估。该合成方法温和、时间短、收率高,适用于构效关系研究。
