First optically active selenurane oxide: resolution of C(2)-symmetric 3,3,3',3'-tetramethyl-1,1'-spirobi [3h,2,1]-benzoxaselenole oxide.
The enantiomers of the first optically active selenurane oxide ever reported, C(2)-symmetric 3,3,3',3'-tetramethyl-1,1'-spirobi[3h,2,1]-benzoxaselenole oxide, were isolated via enantioselective liquid chromatography of the racemate or by spontaneous resolution that occurs during the slow evaporation of its acetonitrile solution or the slow crystallization from the same solvent.
