摘要

Dec., 1948 N ,N'-DIALKYL-N ,N '-DIBENZENESU LFONYLDIAMINOMESITYLENE ... CHa Molecule X was shown to be asymmetri- cal and molecule XI to be symmetrical. Compound X was resolved through its diquinine salt into its enantio- morphs. The d-form was obtained in maximum rotation, [cK]~~D +55', but the 2-form only in a less pure condition, [CK]"D -48'. Compound XI gave only a single salt with quinine and by de- ... M. p. 157-158' M. p. 116-119" acids ...
