This work describes the manufacturing of ribociclib following the concept of an end-to-end continuous-flow process. The active pharmaceutical ingredient (API) is produced in a two-step telescoped flow process with integrated in-line liquid-liquid extraction and semibatch crystallization.
Multi‐step in flow: The palladium‐catalysed acylation of terminal alkynes for the synthesis of yneones as well as their further transformation to various heterocycles in a continuous‐flow mode is presented. Furthermore, an extension of the simple flow configuration that allows for easy batch splitting and the generation of a heterocyclic library is described (see scheme).
