(-)-cis-α-Ambrinol is a natural product present in ambergris, a substance of marine origin that has been highly valued by perfumers. In this paper, we present a new approach to its total synthesis. The starting material is commercially available α-ionone and the key step is an intramolecular Barbier-type cyclization induced by CpTiCl2, an organometallic compound prepared in situ by a CpTiCl3 reduction
(-)-cis-α-Ambrinol 是一种
天然产物,存在于龙涎香中,龙涎香是一种海洋来源的物质,受到调香师的高度重视。在本文中,我们提出了一种新的全合成方法。起始材料是市售的 α-紫罗兰酮,关键步骤是由 CpTiCl2 诱导的分子内 Barbier 型环化,CpTiCl2 是一种通过用 Mn 还原 CpTiCl3 原位制备的有机
金属化合物。
