Improved synthesis of γ-lactones from cyclopropyl cyanoesters
Patel, Nandini C.,Schwarz, Jacob B.,Islam, Khondaker,Miller, Whitney,Tran, Tuan P.,Wei, Yunjing
experimental part, p. 2209 - 2215 (2011/07/07)
Cyclopropyl cyanoesters 2 were reliably converted to c-lactones 4 on treatment with aqueous sulfuric acid. The cyanoesters could be easily prepared from ketones or aldehydes in two steps, making this process particularly attractive from an efficiency standpoint. Copyright
Protolysis of Cyclopropanes with Geminal Electronegative Substituents
Kolsaker, Per,Jensen, Ann Kristin
, p. 345 - 353 (2007/10/02)
Cyclopropanes with geminal ester substituents decompose in anhydrous HClO4/benzene solutions to give substituted γ-lactones; e.g. dimethyl 3,3-dimethyl-2-phenylcyclopropane-1,1-dicarboxylate (1e) is stereospecifically transformed to trans-γ,γ-dimethyl-α-m
