Patel, Nandini C.,Schwarz, Jacob B.,Islam, Khondaker,Miller, Whitney,Tran, Tuan P.,Wei, Yunjing
body text, 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
Unusual iodine catalyzed lactonization of γ-methyl-γ,δ-pentenoic acids: A facile synthesis of γ,γ-dimethyl-γ-butyrolactones
Kim, Kyoung Mahn,Ryu, Eung K.
, p. 1441 - 1444 (2007/10/03)
γ,γ-Dimethyl-γ-butyrolactones were exclusively obtained from γ-methyl-γ,δ-pentenoic acids with a catalytic amount of iodine in good yields in methylene chloride.
