WebHere, we report a sequential C–H/C–C functionalization strategy for the stereospecific synthesis of cis-γ-functionalized cyclobutyl ketones from readily available cyclobutyl aryl ketones. Specifically, a bicyclo[1.1.1]pentan-2-ol intermediate is generated from the parent cyclobutyl ketone via an optimized Norrish-Yang procedure. WebApr 4, 2024 · The CHT Group. Since the foundation of CHT Germany GmbH in Tübingen more than 70 years ago, the CHT Group has developed into a globally active group of companies with a focus on specialty chemicals as function providers, auxiliaries and additives for industrial processes.
