摘要：

A practical and scalable synthetic method to obtain dolutegravir sodium (1) was established starting from the readily accessible material maltol (2). This synthetic method includes a scalable oxidation process of maltol and palladium-catalyzed amidation for introduction of an amide moiety, leading to a practical manufacturing method in short synthetic steps. The synthetic method demonstrated herein enables multikilogram scale manufacturing of 1 of high purity.
