Novel processes for the preparation of peripheral opioid antagonist compounds and intermediates thereto. The compounds prepared by the present processes may be useful, for example, as antagonists to the mu, kappa and delta opioid receptors, and thereby may be useful in the treatment of gastrointestinal motility disorders, and in preventing peripheral opiate induced side effects. The present processes may offer improved yields, chemical or stereochemical purity, ease of preparation and/or isolation of intermediates and final product, and more industrially useful reaction conditions and workability.
该专利介绍了一种制备周围性阿片受体拮抗剂化合物及其中间体的新工艺。该工艺所制备的化合物可以作为mu、kappa和delta阿片受体的拮抗剂,因此可以用于治疗胃肠运动障碍,并预防周围性阿片类药物引起的副作用。该工艺可能提供更高的产率、化学或立体化学纯度、中间体和最终产品易于制备和分离,以及更具工业应用性的反应条件和可操作性。
