    Description / Table of Contents: Polymers of Enzyme-Analogous Structure, III On the Synthesis of Polymerizable Derivatives of D-Glyceric AcidAs starting materials for the introduction of functional groups into polymers in a given spatial relationship a number of polymerizable derivatives of D-glyceric acid were prepared, including D-glyceric (p-vinylanilide) 2,3-O-(p - vinylphenylboronate) (1a). In addition compounds derived from 1a have been prepared in which the amido and the boronate groups are separated from the benzene ring by a spacer of a ethylene group (6,7, and 8). Furthermore the p-vinylphenylboronates of D-glyceric acid esters of methanol (11a), n-octanol (11b), benzyl alcohol (11c), and p-nitrobenzyl alcohol (11d) have been prepared.
    Notes: Als Ausgangssubstanzen zur Einfuhrung von funktionellen Gruppen in Polymere in vorgegebener Nachbarschaftsbeziehung wurden eine Reihe von polymerisierbaren D-Glycerinsäurederivaten synthetisiert, u. a. D-Glycerinsäure-(p-vinylanilid)-2,3-O-(p-vinylphenylboronat) (1a) sowie von 1a abgeleitete Homologe mit einer Äthylengruppe zwischen der Amido- bzw. der Boronatgruppe und dem Benzolring (6, 7 und 8). Außerdem wurden die p-Vinyl-phenylboronate der D-Glycerinsäureester des Methanols (11a), des n-Octanols (11b), des Benzylalkohols (11c) und des p-Nitrobenzylalkohols (11d) dargestellt.

    Notes: The synthesis of a number of new polymerizable monomers containing functional groups is reported [(R)- and (S)-1-(4-vinylphenyl)ethylamine (R)-5 and (S)-5, (R), (S)-N,N-dimethyl-1-(4-vinylphenyl)ethylamine ((R),(S)-6, (R), (S)-trimethyl-1-(4-vinylphenyl)ethylammonium iodide ((R),(S)-7), dihydroxy-6-indenylborane (9), and (S)-2-(6-indentyl)-4-methyl-1,3,2-dioxaborolane (10)]. By racemic resolution optically pure (R)- as well as (S)-1(4-vinylphenyl)ethylamine could be obtained. Furthermore dihydroxy(4,6-dimethyl-7-indeyl)borane (11) was synthesized. The products were characterized by NMR spectroscopy.

    Notes: The influence of the binding group flexibility on the ability for racemic resolution was investigated for binding groups situated in chiral cavities of enzyme-analogously built polymers. D-Glyceric acid was used as a template to introduce dihydroxyborylphenyl-, 4-(2-hydroxyborylethyl)phenyl-, or 5-dihydroxyhoryl-1,2-indanediyl groups into chiral cavities of macroporous polymers. Investigations on the ability for racemic resolution revealed a lower specificity with higher binding group flexibility. On increasing the rigidity compared to the dihydroxyborylphenyl group the specificity is diminished to some extent. This may be attributable to a hindrance of the embedding of the substrate.
