Description

Application

Cyclopropylmagnesium bromide solution has been used in Grignard reaction that finds application as the key step in the preparation of aminopropylindenes, a chemotype of oxidosqualene cyclase (OSC) inhibitors from Grundmann′s ketone. It can react with trimethylborate to form cyclopropylboronic acid, which can undergo Suzuki-type coupling reactions with different aryl, and heteroaryl bromides to form the cyclopropyl adducts.
