(S)-4,4,4-Trifluoro-3-hydroxybutanoic acid was used as a starting material for the synthesis of dendritic branches (16–21, 30–32) which were attached to a chiral triol (6 or ent-6), derived from (R)-3-hydroxybutanoic acid, to give CF3-substituted

Chiral triols 1-3 ("�tris(hydroxymethyl)methane"™ derivatives), prepared from (R)-3-hydroxybutanoic acid and aldehydes, are used as center pieces of dendrimers. The triols may be employed as such or after attachment of spacers containing alkyl or

The first dendrimer with a chiral core and chiral branch units (2) is readily available from triols of the type 1. Attachment of spacer groups or direct etherification of 1 with benzylic bromides lead to first, second, and third generation chiral den
