During these years (1997-2000) in the research area of annonaceous acetogenins 5 natural products and a number of chiral-pure analogs of annonaceous acetogenins have been synthesized using sugars as the starting materials. Their high activity and selectivity against cell line of colon tumor and a relationship between activity and configuration have been found too. In the respect of inhibitor of sialidase two new methodologies for the synthesis of chiral-pure 3-deoxy-ulosonic acid using hetero-Diels-Alder reaction or asymmetric propargylation as the key reaction were developed. On the topic of anti-leukemia marine natural product clavulactone a synthetic method based on the free radical cyclization and starting from sugar has been developed. In other title of PKC inhibited agent sphingosine a new synthetic route with SN2' as the key reaction has also been disclosed.

项目期间（1997-2000）在番荔枝内酯方面从糖出发合成了五个天然产物和一批手性纯的类似物，它们对肠癌细胞有很高的活性和选择性，并与构型有关；在唾液酸酶抑制剂方面发展了二类全新手性纯高碳糖的合成方法－杂原子D－A反应或丙炔基不对称加成为关键的反应；抗白血病海洋天然产物群柱虫内酯方面研究了由糖出发和自由基环化反应的合成方法；对PKC 起抑制作用的鞘氨醇方面也开创了新的合成途径－由糖出发并以SN2'反应为关键反应。

Dihydro-5H-cyclopentanopyridine, a key intermediate of Cefpirome, was synthesized from cyclopentanone and propargylamine under autoclave prompted by copper chloride.

以环戊酮和丙炔胺为原料，在高压釜中用氯化亚铜催化合成头孢匹罗关键中间体6，7-二氢-5H-环戊烷并吡啶。

After the click reaction of the SCL micelles and azide-terminus PNIPAM homopolymer, the novel PNIPAM-functionalized SCL micelles with pH-responsive cores and outer thermosensitive coronas were prepared, which was investigated act as excellent candidate of nanosized drug delivery vehicles. Finally, two types of novel shell cross-linked micelles in aqueous solution were prepared from these remarkable PMEO_2MA-b-P(DMA-co-QDMA)-b-PDEA triblock copolymers by cross-linking the inner P(DMA-co-QDMA) shell of micelles upon the addition of diazide tetra derivative in the presence of copper catalyst using click chemistry.

另外，还可以使用溴丙炔对ATRP聚合出的PMEO_2MA-b-PDMA-b-PDEA三嵌段的中间PDMA嵌段进行部分季胺化，这样可以利用两端叠氮化的四甘醇来交联由PMEO_2MA-b-PDMA-b-PDEA在不同条件下形成的两种分别以PMEO_2MA或PDEA为核的胶束，从而实现了从同一个聚合物直接在水溶液中得到两种内核不同敏感的壳交联胶束。

Some products included methoxy group, naphthyl and heterocyclic aromatic moieties, and some were borne with two 1-propynyl groups. It is more important that compounds bearing halogens were also synthesized via this protocol.

运用此法不仅合成出一些含有醚键、萘环、杂环以及含有两个1-丙炔基的化合物，重要的是芳环上含有卤原子的化合物也能顺利地合成出来。

The measuring of conductivity of the copolymers also indicates that addition of phthalie acid did not destroy the conjugation system of homopolymer of propargyl alcohol.

产物电导率的测量亦说明邻苯二甲酸的加入，并没有破坏聚丙炔醇的共轭体系，但共聚物的电导牢随邻苯二甲酸的含量增加而略有降低。

The IR spectra of the copolymers demostrate that copolymers were polycondensation product of homopolymer of propargyl alcohol with phthalic acid.

IR光谱证明了共聚物是邻苯二甲酸与丙炔醇均聚物的缩合产物。

The thesis is divided into two areas: The first area investigated using gold, silver complex to catalyze the cyclization of propargyl alcohol molecules to produced the cyclohexanone products in high yield at room temperature.

题目将分成两个部份：第一个部份主要研究金属金和金属银错合物催化丙炔醇类分子的环化反应，在室温下反应产生高产率之环己酮产物。

The inhibition of propargyl alcohol for 1Cr18Ni9Ti stainless steel in hydrochloric acid solution is studied with the cyclic voltammetry and ellipsometry.

采用循环伏安法和椭圆偏振光谱法，研究了丙炔醇(Propargylalcohol，PA)对 1Cr18Ni9Ti不锈钢在含有氯离子的腐蚀环境中的缓蚀作用，实验表明Cl-能使 1Cr18Ni9Ti不锈钢发生点蚀，而缓蚀剂PA对不锈钢受到Cl-的腐蚀起抑制作用。

A corrosion inhibitor CH - 10 used in high temperature acid treatment was obtained by compounding this cationic Mannich base with propargyl alcohol.

针对Mannich碱型缓蚀剂存在的溶解性不好和缓蚀率不高等问题，以甲醛、环己酮和苯胺为原料，合成了一种Mannich碱型缓蚀剂CH-9，将其阳离子化后，再与丙炔醇复配，得到了阳离子型高温酸化缓蚀剂CH-10。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
