ENANTIOMERICALLY PURE DENDRIMERS BASED ON A TRANS-3,4-DIHYDROXYPYRROLIDINE

The synthesis of the first and second generation of enantiopure dendri mers based on a chiral trans-3,4-dihydroxypyrrolidine is reported. Ben zenepolycarboxylic acids were used as central nucleus to afford linear and radial growth, and terephthalic acid was used as spacer between t he pyrrolidine nuclei. The analysis of the chiroptical properties ([al pha](D), circular dichroism) of these new dendrimers suggests that tho se with radial growth present a self organisation of chiral units.
