Practical Synthetic Method for the Preparation of Pyrone Diesters: An Efficient Synthetic Route for the Synthesis of Dolutegravir Sodium

A highly efficient and practical synthetic method for the preparation of pyrone diesters was established. The pyrone diester 3c can be prepared from readily available starting materials on a multihundred gram scale. The pyrone diester 3c can easily be converted to dolutegravir sodium (1). The synthetic route demonstrated herein provides an efficient and atom-economical synthetic method for preparing this potent anti-HIV agent.

Improved method for synthesizing dolutegravir

The invention relates to an improved method for synthesizing dolutegravir and belongs to the field of medicinal chemistry. The method takes maltol (compound 1) as a raw material, and a target is synthesized by the following route. The process raw material is cheap and easy to obtain, a reaction solvent can be recycled, the post-treatment operation is simple, the yield and the purity are high, especially the carbamoylation and debenzylation reaction are carried out in one step, the synthesis route is simplified, the cost is reduced, and the large-scale industrial production is facilitated.

PROCESSES AND INTERMEDIATES FOR CARBAMOYLPYRIDONE HIV INTEGRASE INHIBITORS

Processes are provided which create an aldehyde methylene, or hydrated or hemiacetal methylene attached to a heteroatom of a 6 membered ring without going through an olefinic group and without the necessity of using an osmium reagent. In particular, a comopound of formula (I) can be produced from (II) and avoid the use of an allyl amine: (formulae I and II) where R, P 1 P3, R3 and Rx are as described herein.
