    Notes: A new type of polyvinylsaccharide with a C—C bond between the pendent sugar and the backbone was prepared. Without use of protecting groups N,N-dimethylbarbituric acid was used to link sugars directly to a polymerizable group. Homo- as well as copolymers were prepared by radical initiation. The barbiturate ring of the polymer undergoes a specific base-catalyzed ring cleavage to give highly water-soluble polymers. Also in copolymers with less than 32 mol-% styrene residues water solubility is attained due to the newly formed diamide groups.

    Notes: 3,4-O-Cyclohexylidene-D-mannitol 1,2:5,6-bis-O-[(4-vinylphenyl)boronate] (M 1) was copolymerized with methyl methacrylate (MMA) in presence of AlEt1,5 or SnCl4. The expected alternating bis(4-vinylphenylboronic acid)-MMA triad structures were only formed to a lesser extent. Instead, predominantly alternating 4-vinylphenylboronic acid-MMA structures were obtained. Since no crosslinking was observed, a cyclocopolymerization must have occurred. In this case an MMA unit is inserted between the two styrene residues of M 1, thus forming a 21-membered ring system. Copolymerization forming alternating 4-vinylphenylboronic acid-MMA diads is apparently even faster than the direct copolymerization forming distyryl diads. After removal of the template (3,4-O-cyclohexylidene-D-mannitol), these copolymers still show pronounced optical activity and circular dichroism with a negative Cotton effect at 233 nm. After deboronation of the copolymers, optically active, predominantly alternating styrene-MMA copolymers are obtained.

    The preparation of new types of polymerizable vinyl sugars with C—C bonds between sugar and double bondIn memory of Jürgen Schmid (1996)

    Notes: The syntheses of new types of vinyl sugars are described whose vinyl groups are connected with the monosaccharide by a C—C bond. Such monomers can be polymerized by radical as well as by anionic initiation. Starting from D-mannitol, D-gluconolactone, D-galactose, and D-fructose, the isopropylidene-protected aldehydes (R)-2,3-isopropylidene-D-glyceraldehyde (3), 2,3;4,5-di-O-isopropylidene-aldehydo-D-arabinose (4), 1,2;3,4-di-O-isopropylidene-α-D-galacto-hexodialdo-1,5-pyranose (5), and 2,3;4,5-di-O-isopropylidene-β-D-arabino-hexosulo-2,6-pyranose (6) were prepared. Grignard reaction of the aldehyde compounds with 4-vinylphenylmagnesium chloride in tetrahydrofuran (THF) yielded the new styryl monomers of type 1, in each case as a mixture of two diastereoisomers. The corresponding reaction with vinylmagnesium bromide furnished a mixture of two diastereoisomeric allyl alcohol derivatives. Subsequent Swern oxidation (DMSO/(COCl)2) gave the vinyl ketones of type 2. A scale-up procedure (20 L flask) allowed eight different monomers to be prepared on a 50-200 g scale. Furthermore, the synthesis of the 2,3;4,5-di-O-isopropylidene-β-D-fructopyranose could be considerably improved.

    Synthesis and polymerization behavior of 2,3-dihydro-1,4-dioxin-2-one and its 3-methyl derivative (1996)

    Notes: The hitherto unknown 2,3-dihydro-1,4-dioxin-2-one (7) and its 3-methyl derivative 8 have been synthesized for the first time. The olefinic double bond is inserted into the saturated 1,4-dioxanone precursors 3 and 6a/b by a retro-Diels-Alder reaction in the last step of the synthesis. The 1,4-dioxanone systems of 3 and 6 are prepared by reacting a vicinal dialkoxide with α-halogenated acyl halides, thus forming the ester and the ether bond in a one-pot reaction. Monomers 7 and 8 are polymerized by cationic initiation. The resulting products undergo fragmentation to form oligomers in the presence of protic solvents, indicting that ring-opening polymerization of the δ-lactone apparently leads to polyester chain segments.

    Characterization of MgO layers on different alumina and glass substrates by grazing incidence diffractometry and grazing incidence X-ray reflectometry (1995)

    Notes: Magnesium oxide thin films were deposited at an average evaporation rate of 1.8 nm s-1 onto different crystalline alumina substrates and amorphous float glass. The deposits were made in an electron-beam evaporator at substrate temperatures between 25°C and 190°C under different oxygen partial pressures. Films of 0.1, 0.5 and 1 μm thickness were deposited. These coatings were investigated by grazing incidence diffractometry (GID) to vary the depth of penetration. For films 0.1 μm thick the additional use of grazing incidence x-ray reflectometry (GIXR) was possible. The deposite films were polycrystalline with different 〈100〉 textures depending on the substrate temperature. All the MgO thin-film reflexes measured were strongly broadened compared with the reflexes of a standard polycrystalline MgO material. The crystal size and the microstrain of the MgO coatings were calculated by profile analysis using the Fourier transformation method. It was demonstrated that the x-ray profiles of the MgO reflexes are influenced by the roughness of the substrate surface. Only small gradients were found in the particle sizes and microstrains within the deposited films. The oxygen partial pressure did not significantly influence the film properties measured by GID. The GIXR roughness and mass density measurements agreed with the results of GID. Magnesium oxide films deposited at higher temperatures show a diminished crystallinity and less interface roughness.

    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: Optically active poly(styrene-co-methyl methacrylate) and poly(styrene-co-methacrylonitrile) were obtained by means of asymmetric copolymerization of 3,4-cyclohexylidene-D-mannitol-1,2; 5,6-bis{O-[(4-vinylphenyl)boronate]} (1) with methyl methacrylate and methacrylonitrile, respectively, removal of the D-mannitol template and splitting off boric acid from the resulting copolymers. By polymer analogous reactions, various functional groups were introduced to obtain optically active functional vinyl copolymers. The polymers were characterized by spectral and other analytical methods.

    Notes: The asymmetric synthesis of a-amino acids within chiral cavities of special crosslinked polymers was investigated. Chiral cavities prossessing definite shapes and specific arrangements of the functional groups were obtained by preparation of crosslinked polymers in the presence of suitable templates. Best results with an enantiomeric excess of 36% were obtained by using a polymer which was imprinted by L-DOPA. The cavities contained a salicylaldehyde and a phenylboronic acid moiety each. L-Threonine was prepared by reaction of the polymer bound anion of a salicylideneglycine nickel complex with acetaldehyde.

    Notes: New types of macroporous polymers containing chiral cavities were prepared for the racemic resolution of free sugars. As template monomers 6-O-methyl- and 6-O-benzyl-αD-galactopyranose 1,2;3,4-tetra-O-bis(4-vinylphenylboronate) (3c and b) as well as 1-O-methyl- and 1-O-benzyl-βD-fructopyranose 2,3;4,5-tetra-O-bis(4-vinylphenylboronate) (4c and b) were copolymerized with a large amount of ethylene dimethacrylate. After splitting off the respective templates, these polymers were used for the racemic resolution of the racemates of D,L-galactose and D,L-fructose, and also the racemates, of 1-O-methyl- and 1-O-benzyl-D,L-fructose. The polymer prepared from 3b yielded the highest selectivity for the racemic resolution of D,L-galactose. In the case of fructose the benzyl-ether-imprinted polymers yielded the highest selectivity, especially for 1-O-methyl-D,L-fructose separation. Polymers imprinted with D-galactose derivatives showed inverse selectivity by preferably absorbing L-fructose from the racemate. Polymerization at lower temperatures usually yielded more selective polymers.
