Mild and Robust Stille Reactions in Water using Parts Per Million Levels of a Triphenylphosphine-Based Palladacycle

An inexpensive and new triphenylphosphine-based palladacycle has been developed as a pre-catalyst, leading to highly effective Stille cross-coupling reactions in water under mild reaction conditions. Only 500–1000 ppm of Pd suffices for couplings involving a variety of aryl/heteroaryl halides with aryl/hetaryl stannanes. Several drug intermediates can be prepared using this catalyst in aqueous nanoreactors formed by 2 wt % Brij-30 in water.

Development of a Convergent Large-Scale Synthesis for Venetoclax, a First-in-Class BCL-2 Selective Inhibitor

The process development of a new synthetic route leading to an efficient and robust synthetic process for venetoclax (1: the active pharmaceutical ingredient (API) in Venclexta) is described. The redesigned synthesis features a Buchwald-Hartwig amination to construct the core ester 23c in a convergent fashion by connecting two key building blocks (4c and 26), which is then followed by a uniquely effective saponification reaction of 23c using anhydrous hydroxide generated in situ to obtain 2. Finally, the coupling of the penultimate core acid 2 with sulfonamide 3 furnishes drug substance 1 with consistently high quality. The challenges and solutions for the key Pd-catalyzed C-N cross-coupling will also be discussed in detail. The improved synthesis overcomes many of the initial scale-up challenges and was accomplished in 46% overall yield from 3,3-dimethyldicyclohexanone (6), more than doubling the overall yield of the first generation route. The new process was successfully implemented for producing large quantities of 1 with >99% area purity.
