    Cereal grain resorcinolic lipids: mono and dienoic homologues are present in rye grains
    摘要:
    Analyses (UV, IR, H-1-NMR, MS) of the main phenolic fractions isolated by sequential separation on normal-phase and by argentation chromatography on silica gel confirmed the presence of monoenoic and dienoic homologues of 1,3-dihydroxy-5-n-alkylbenzene in acetone extracts from rye grains. Conversion of mono and dienoic homologue dimethyl ethers to the cis-diols with osmium tetroxide, transformation of the diol to the acetonide with acetone and subsequent MS analysis of resulting derivatives showed that the breakdown pattern for the monoenoic homologues was consistent with a double bond in all the homologous chain length at the 8-position. For dienes, the results were not so conclusive, although the 8- and 11-positions appear to be the favoured ones. It has been also shown that rye 5-n-ketoalkylresorcinols contain a previously unobserved C17 homologue. All identifications were confirmed by comparison with synthetically obtained C19:0 and C21:0 5-n-alkylresorcinols and a 5-n-(2-keto-heptadecyl)resorcinol. Other minor phenolic components present in the acetone extract were identified as homologous 5-n-(2-hydroxyalkyl)resorcinols.

  • Soluble, highly conjugated derivatives of polyacetylene from the ring-opening metathesis polymerization of monosubstituted cyclooctatetraenes: synthesis and the relationship between polymer structure and physical properties

    Abstract : Using well-defined tungsten-based olefin metathesis catalysts, a family of partially substituted polyacetylenes have been synthesized via the ring-opening metathesis polymerization (ROMP) of monosubstituted cyclooctatetraenes (RCOT). These polymers are highly conjugated as evidenced by their visible absorption maxima, they are of high molecular weight as evidenced by gel permeation chromatography
    摘要 : 使用定义明确的基烯烃复分解催化剂,通过单取代环辛四烯 (RCOT) 的开环复分解聚合 (ROMP) 合成了一系列部分取代的聚乙炔。这些聚合物是高度共轭的,如它们的可见吸收最大值所证明的那样,它们具有高分子量,如凝胶渗透色谱所证明的那样,并且该家族的大多数成员以合成时的主要顺式形式可溶。聚合物可以异构化为主要使用热或光进行转化。通过可见吸收光谱监测热异构化的速率。通常,紧邻主链的含有二级或三级基团的聚合物仍以反式形式可溶,并且在大多数情况下仍高度共轭。
