Seeking for Selectivity and Efficiency: New Approaches in the Synthesis of Raltegravir

Abstract

The present work describes the development of an improved synthesis of active pharmaceutical ingredient raltegravir. The isolation of a new process intermediate and the newly developed conditions solve the issue of selectivity typical of this production process, with no need for the use of protecting groups, making the present route more efficient and sustainable than what was reported before. Efficiency comparisons with the previous processes confirm the result here obtained.
