Usage

Uses

1. Used in Pharmaceutical Industry:
1-((4'-chloro-5,5-dimethyl-3,4,5,6-tetrahydro-[1,1'-biphenyl]-2-yl)methyl)piperazine dihydrochloride is used as an intermediate in the synthesis of Venetoclax (A112430) for its potent antitumor activity. Venetoclax is a selective BCL-2 inhibitor that targets and disrupts the function of the BCL-2 protein, which is overexpressed in various types of cancer cells, leading to their survival and resistance to apoptosis. By inhibiting BCL-2, Venetoclax promotes apoptosis and reduces tumor growth.
2. Used in Anticancer Applications:
1-((4'-chloro-5,5-dimethyl-3,4,5,6-tetrahydro-[1,1'-biphenyl]-2-yl)methyl)piperazine dihydrochloride contributes to the development of Venetoclax, which is used to treat chronic lymphocytic leukemia (CLL) and estrogen receptor-positive breast cancer. Venetoclax has shown significant efficacy in these cancer types by selectively targeting cancer cells while sparing healthy cells, such as platelets, which is a significant advantage over traditional chemotherapy treatments.
3. Used in Drug Development and Research:
In addition to its role in the synthesis of Venetoclax, 1-((4'-chloro-5,5-dimethyl-3,4,5,6-tetrahydro-[1,1'-biphenyl]-2-yl)methyl)piperazine dihydrochloride may also be utilized in the development and research of other BCL-2 inhibitors and related compounds. Its unique molecular structure and properties make it a valuable tool for exploring new therapeutic strategies and potential applications in oncology and other areas of medicine.

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.
