The total synthesis of (-)-thysanone is described. The key step involves the addition of an o-toluate anion to a lactone to create the naphthopyran framework (Staunton-Weinreb annulation). This synthesis further confirms the absolute stereochemistry of the natural product to be 1R,3S. thysanone - Staunton-Weinreb annulation - total synthesis - natural products - polycycles
描述了(-)-胸苷的全合成。关键步骤涉及向内酯中添加邻甲苯甲酸根阴离子以形成萘并吡喃骨架(Staunton-Weinreb环空法)。该合成进一步证实天然产物的绝对立体化学为1 - [R,3小号。 胸苷-Staunton-Weinreb环化-全合成-天然产物-多环化合物
