Popis: Two benzyl groups can be assembled with a chiral shape in the 6 H , 12 H -Dibenzo[ b,f ][1,5]dithiocine structure which can be resolved into its antipods via enantioselective oxidation to the bissulfoxide. The latter affords one single diastereoisomer in the methylation of its bis-anion. The two sulfur atoms serve as linking agents, holder and transmitter of chirality, and activating functionalities.
