Synthesis of cyclopropanes via iodine–magnesium exchange between 3-iodomethyl-1-oxacyclopentanes and organomagnesium reagents
摘要:
Iodine-magnesium exchange occurs upon treatment of 3-iodomethyl-1-oxacyclopentanes with alkyl Grignard reagents or trialkylmagnesate. The resulting organomagnesium compounds undergo intramolecular nucleophilic substitution in ether to afford cyclopropane skeletons in a stereoselective manner. (C) 2003 Elsevier Ltd.
