Abstract
An asymmetric synthesis of cis-1,2-diaryltetralin (2), a key chiral intermediate in the synthesis of Vepdegestrant (1), an orally available PROTAC being evaluated for the treatment of ER+/HER2- breast cancer, is reported. Chirality is initially introduced via a catalytic enantioselective intramolecular Corey-Chaykovsky epoxidation utilizing isothiocineole, a chiral sulfide. Although several asymmetric intermolecular epoxidations using chiral sulfides have been reported, our approach represents a unique intramolecular variant. The subsequent introduction of the cis-1,2-diaryl motif is achieved via diastereoselective hydrogenation.
期刊介绍：
The journal Organic Process Research & Development serves as a communication tool between industrial chemists and chemists working in universities and research institutes. As such, it reports original work from the broad field of industrial process chemistry but also presents academic results that are relevant, or potentially relevant, to industrial applications. Process chemistry is the science that enables the safe, environmentally benign and ultimately economical manufacturing of organic compounds that are required in larger amounts to help address the needs of society. Consequently, the Journal encompasses every aspect of organic chemistry, including all aspects of catalysis, synthetic methodology development and synthetic strategy exploration, but also includes aspects from analytical and solid-state chemistry and chemical engineering, such as work-up tools，process safety, or flow-chemistry. The goal of development and optimization of chemical reactions and processes is their transfer to a larger scale; original work describing such studies and the actual implementation on scale is highly relevant to the journal. However, studies on new developments from either industry, research institutes or academia that have not yet been demonstrated on scale, but where an industrial utility can be expected and where the study has addressed important prerequisites for a scale-up and has given confidence into the reliability and practicality of the chemistry, also serve the mission of OPR&D as a communication tool between the different contributors to the field.
