Cyclopentane, methylene-: ACTIVE
Applications
UsesMethylenecyclopentane has been used in total synthesis of (±)-cephalotaxin.
General DescriptionHydration rate of methylenecyclopentane has been measured spectrophotometrically in aqueous perchloric acid. Trost′s palladium-mediated methylenecyclopentane annelation to the nitroalkene yields methylenecyclopentane derivative.
