Tetrahydroxanthenones represent the core of many natural products, most of which exhibit interesting biological activities. In the course of our synthetic efforts towards the total synthesis of the secalonic acids, which contain two of these tricyclic units, we have investigated the influence of substituents on the one-step domino oxa-Michael addition–aldol reaction leading to tetrahydroxanthenones
四氢氧杂蒽酮代表了许多天然产物的核心,其中大部分表现出有趣的生物活性。在我们对含有两个三环单元的癸二酸进行全合成的过程中,我们研究了取代基对一步多米诺氧杂-迈克尔加成-羟醛反应导致四氢氧杂蒽酮的影响。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)
