In the first part, we studied the possibility of allyl as the protection group of the hydroxyl in nucleosides.

烯丙基作为糖化学中的一种常用保护基在核酸化学中有一定的应用，曾有人将它作为磷酸酯键及碱基环上羰基的保护基，但作为核苷糖环羟基的保护基还未有研究。

There is no electron transfer from tetrakis(2-thienyl)tetrathiafulvalene to [60]fullerene containing piperidinoxanthate dyad in benzonitrile in steady-state.

四硫富瓦烯及其衍生物是良好的有机导体及电子给体，噻吩基取代的四硫富瓦烯可作为合成含噻吩及四硫富瓦烯两种电子给体的聚合物的单体。

The epoxidation of of various olefins was carried out using LDH-F with Mg/Al=5 as the catalyst and H2O2 and benzonitrile as the oxidants. This catalytic system has excellent catalytic activity. The conversion and selectivity are both above 95% when using styrene, indene, allyl alcohol, and allyl chloride as the substrates.

Results: expression of inos proteins was seen on day 1 following the control stent implanting, developed on day 3, peaked on day 10 and lasted till day 28. inos expressions at all time points in diallyl trisulfide coated stent group were higher than those in control stent group. compared with normal blood vessel tissue, the no production after stenting decreased on day 1, increased on day 3, maximized on day 10, went down to its pre stenting level on day 28. at all time points, no levels in allitridi stented sites were higher than those in control stented sites.

结果： 对照支架组术后1 d血管壁中有少量inos蛋白表达，3 d表达增加，10 d达高峰，28 d时仍有表达，二烯丙基三硫化物涂层支架组inos蛋白在各时间点的表达量均高于对照支架组；对照支架组术后1 d时no生成量低于正常组织，3 d时no水平升高，10 d时最高，28 d时降至基线水平，二烯丙基三硫化物涂层支架组各时间点的no水平明显高于对照支架组。

Stented sites. CONCLUSION: Diallyl trisulfide coated stent could significantly enhance the iNOS expression and NO production, which may play an important role in inhibiting neoin????timal hyperplasia.

二烯丙基三硫化物涂层支架可显著增加iNOS表达，并提升NO产量，提示二烯丙基三硫化物涂层支架可能是抑制内膜增生的一个重要机制。

Then, it was condensed with-valine methyl ester to form a chiral imine, which was reacted with allyl zinc bromide in the presence of CeCl3·7H2O to afford the corresponding chiral homoallylic amine with high optical activity.

-N-Boc-3-苯基-2-氨基丙醛与-缬氨基酸甲酯缩合生成手性亚胺，在七水合三氯化铈（CeC13·7H2O）催化以及底物的手性诱导作用下，该手性亚胺与烯丙基溴化锌经不对称加成反应合成了高光活性的单烯丙基化手性胺。

In addition, 65% ee was obtained for 1, 3-dimethylprop-2-enyl acetate. Interestingly, the reactivities of these ligands are all very high.

对于1， 3-二苯基烯丙基醋酸酯的烷基化和胺化反应， ee 值最高分别为93%和98%，此外，在对1， 3-二甲基烯丙基醋酸酯的烷基化反应中 ee 值最高也可达65%。

In this paper,the physical propertites and reactivity of allyl xy lob resin are introduced, and a new matrix resin— allyl xylok ／BMI resin system is showed.The properties of this resin system and its fiber reinforced compression moloding materials.
