By comparing with known compound A2'P 5'A,it was shown that two ribose rings of a and b adopt predominantly S conformation at 18℃, but with elevation of temperature, the N conformation of some ribose ring increaed: the torsional angles e' and β of the phosphate backbone were estimated to have a change of +2° and ±12°respectively; two ribose rings of both A2'P(CH3)5'A and were partially overlapped and the degree of overlapping of was smaller than that of the : with increasing of temperature, the adenine moiety of A2'P(CH3)5'A showed a stronger tendency to unstack than A2'P(CH3)5'A .

它们与A2′P5′A相比发现：(1)在18℃时两个核糖环是S型构象占主要成分，但随温度升高有的核糖环趋向于转化成N型构象；(2)磷酸骨架的扭角ε′和β分别改变±2°及±12°；(3)A2′P(CH_3)5′A和的两个核糖环均属部分重叠，并且前者的重叠程度小于后者；(4)随着温度升高，A2′P(CH_3)5′A比A2′P(CH_3)5′A有着更强的去堆积效应。

The left coumarin moiety was assembled by aldol condensation and then intramolecular esterification in one pot, which would be a popular method to build 3-substituted coumarins later.

最终，我们以12%的总产率和98.7%的ee值首次实现了-rutamarin的手性全合成；同时，我们还以17%的高产率实现了其消旋体的合成，比之以前文献报道的产率提高了2.5倍。

This nonmutagenic amino compound 4 (via the investigation into Salmonella/mammalian microsome assay) was also employed as diazo moiety coupling with acet-J-acid to form a diazo acid dye 5. The new dye 5 can color wool at 2% or silk at 3% o. w. f. into black one. The investigation of the uptake of 5 and its color appearance showed that it was assigned to an acid bluish black dye and its blackness was more excellent than that of Acid Black 10B.

经过Salmonella／mammalian microsome assay测试，4表现为非诱变性，用4与乙醯J－酸作用得到新型双偶氮酸性染料（5）。5对羊毛和丝绸分别在2%与3%色度下浸染都得到黑色染样，考察了5的上染曲线，并对染样进行了测色研究，发现该染料属於酸性蓝黑染料，其黑度优於目前市场上流行的酸性黑10B。

In the course of our study the chemistry of arenes contaning allylic acetates moiety under the catalysis of palladium, we found an efficient synthesis of benzocycles via intramolecular Friedel-Crafts reaction of halogen free 6-acetoxy-4alkenyl arens.

我们在设计钯催化的碳—氢键活化时，发现了含有烯丙基醋酸酯侧链的芳烃的三氟醋酸促进的分子内的Friedel-Crafts反应，从而为有效合成苯并六元环结构提供了一个方便的方法。

After UVB radiation for 3 h, unstacking of the AT base pairs and the cytosine ring takes place and some severe damage to the thymine moiety occurs, and some base pairs have been modified.

经过3h UVB照射，AT碱基对和和胞嘧啶环的堆叠程度有所瓦解，一些碱基对受到修饰。

Result: Immersion test with JJ18 broth showed that the active components were extracellular moiety of the broth and that 10% concentration solution could kill nearly 90% snail immersed after 72 h,the salified broth has favourable thermostabily and photostability and showed that JJ18 has stable passage and its active components concentrate in the extract of n-butanol.

结果：JJ18菌株发酵液的活性成分集中在胞外液，当胞外液浓度10%时，72h杀螺率接近90%，且发酵外液成盐后有良好的耐热性，强光照下7 d内活性物质基本不改变，菌株传代稳定，杀螺活性成分集中在正丁醇萃取部位。

Thermal analysis showed that all of the four polymers have high thermal stability with T_g higher than 200 °C. The absorption spectra of PDOPPF and PDAOPF-PPF showed fine peaks resulting from pyrenes at C9 of the fluorene moiety and PDOFP and PDAOPF-P showed red-shift compared to polyflurenes.
