Abstract:

The fluorine-containing lactones are often present in natural organic- compounds. In this study the structures of three fluorine-containing lactones were determined using the NMR techniques(1H NMR,13C NMR,1H -1H COSY,NOESY,HMB C,HMQC). Two-dimensional NOESY was especially useful for providing information on the stereo configuration of the compounds. Knowing the structures can be help ful in studying the mechanism of chemical reactions involving fluorine-containi ng lactones.

Key words: NMR spectroscopy, fluorine-containing lactones, stereo configuration
