SYNTHESIS AND CHIROPTICAL PROPERTIES OF OPTICALLY-ACTIVE LAYER-BLOCK DENDRIMERS

The syntheses of two different homochiral, layered-block dendrimers 1 and 2 are reported; the chiral units used in the construction of these two first-generation dendrimers are derivatives of (D)- and (L)-tarta ric acid; for these low generation dendrimers, the optical rotation st rength of the (D)-tartaric derived chiron cancels out that of its anti podal (L)-tartaric derived chiral unit.
