Synthesis of 5-(perfluoroalkylmethyl)-1,3-dioxolan-4-ones
2010
Abstract Acid catalysed condensation of F -alkyl α-hydroxy acids with simple aldehydes or ketones gave F -alkyl 1,3-dioxolan-4-ones. When BF 3 ,OEt 2 was used as the catalyst, the condensation products were obtained in moderate to good yields and the “cis” isomers are largely favoured, while with HOTs/H 2 SO 4 as catalyst, poor yields and lower stereoselectivities were observed.
