摘要
Cyclopropyl ketones are readily cleaved under neutral conditions at room temperature by the combined action of acetyl methanesulfonate and nucleophiles such as Br−, I−, and MsO−. The high‐yield reaction involves regiospecific enol acetate formation with a stereoselectivity of nucleophile addition which is compatible with an SN2‐type opening of the cyclopropyl ring.
