Abstract

The 1H and 13C NMR chemical shifts of the aldose reductase inhibitor 4(S)-2,3-dihydro-6-fluoro-2(R)-methylspiro[chroman-4, 4′-imidazoline]-2′,5′-dione, methylsorbinil, and its seven synthetic intermediates, have been completely assigned on the basis of DEPT, COSY, g-HSQC and g-HMBC. All C-F coupling constants from one-bond to four-bond in the 13C NMR spectra and H-F and H-H coupling constants from three-bond to four-bond in 1H spectra were obtained.
