An asymmetric synthesis was developed for the production of a prostaglandin D2 receptor antagonist for the treatment of allergic rhinitis. The stereogenic center was set using asymmetric allylic alkylation chemistry, and the core of the structure was constructed via Pd-catalyzed N-cyclization/Heck methodology. The synthesis relies on a late stage indoline oxidation which does not racemize the product
开发了一种不对称合成物,用于生产前列腺素D 2受体拮抗剂,用于治疗变应性鼻炎。使用不对称烯丙基烷基化化学方法设定立体异构中心,并通过Pd催化的N-环化/ Heck方法构建结构的核心。合成依赖于后期的二氢吲哚氧化,不会使产物外消旋。
