in aqueous THF is highly diastereoselective. The obtained product has been converted in four steps into a spiro lactone previously transformed into syributins and secosyrins. This remarkably short reaction sequence constitutes therefore a formal synthesis of these compounds and provides also a promising synthetic approach towards the syringolides.
被保护的d-木酮糖衍生物在THF水溶液中的铟介导的烯丙基化是高度非对映选择性的。所获得的产物已通过四个步骤被转化为螺内酯,该螺内酯先前已被转化为syributins和cocosyrins。因此,这种非常短的反应序列构成了这些化合物的正式合成,并且也为丁香内酯提供了有希望的合成方法。
