The enantiomers of a C-2-symmetric spirobisalkoxyselenurane, 3,3,3',3'-tetramethyl-1,1'-spirobi[3H,2,1]-benzoxaselenole, have been isolated for the first time via chromatographic resolution of the racemate using a chiral HPLC column. The isomers were further characterized by H-1 NMR and CD spectroscopic measurements. (C) 2002 Elsevier Science Ltd. All rights reserved.
