A new antibiotic natural product, ravynic acid, has been isolated from a Penicillium sp. of fungus, collected from Ravensbourne National Park. The 3-acylpolyenyne tetramicacid structure was definitively elucidated via synthesis. Highlights of the synthetic method include the heat induced formation of the 3-acylphosphorane tetramicacid and a selective Wittig cross-coupling to efficiently prepare the
从青霉菌属中分离出一种新的抗生素天然产物雷维酸。从拉文斯伯恩国家公园收集的真菌。通过合成确定了3-酰基多烯炔四酸的结构。合成方法的亮点包括热诱导的3-酰基磷烷四甲酸的形成和选择性Wittig交叉偶联,以有效地制备天然化合物的碳骨架。事实证明,该天然化合物抑制金黄色葡萄球菌的生长至2.5 µg mL -1的浓度。
