Several methods have been assayed for the anchoring of chiral fragment
s derived from tartaric acid to polystyrene/divinylbenzene resins. In
order to further modify the initially anchored chiral groups, binding
to the polymer backbone through an ether linkage is preferred to the u
sual acetalic linkage. Resins containing different chiral groups have
been prepared with degrees of functionalization ranging from 0.5 to 0.
8 meq/g (DF = 0.05-0.11). The use of the O-monobenzyl ether of dimethy
l tartrate gives the best results for the initial anchoring reaction.
