Whenpyridine was used as reductive decomposing agent, the expecting cholest-4-en-3,6-dione-22-al was obtained. However, when Zn/HOAc was used to decomposethe ozonide, C-4,5 double bond was further reduced to give cholest-3,6-dione-22-al as main product. 2 For the side-chain construction of compound (1), the solid-liquid phase-transfer Wittig reaction was used. When (3-methyl-2-oxobutyl)-triphenylarsonium bromide was used as reagent, the reaction can be carried out inmild reaction condition and the yield is higher than that when phosphorane wasused.

但使用Zn／HOAc作为分解剂时，却得到其氢化产物胆甾-3， 6-二酮-22-醛；2在甾体支链引入过程中，采用固-液相转移Wittig反应的方法，用(3-甲基)-2-氧丁基三苯基溴化胂作为试剂，反应在非常温和的条件下便可完成，而且产率比传统采用膦烷的方法更高；3在对某些甾酮化合物的选择性还原反应研究时，发现在〓还原体系中，当加入某些金属离子后，反应有更好的区域选择性和立体选择性。

After that, we found that TEA has more intense effect in photoinitiate process and more effective in transferring the resultant of dye, while the main effect of DPI is in the photopolymerization's transferring process, DPI can effectively increase the quantum yield efficiency and make the radical of monomer's more stable.

此外，研究发现，TEA在光引发阶段有更强的作用，并且传输染料的生成物时更有效，而DPI的主要作用是在光聚合的传输阶段，DPI能够有效提高光聚物的量子产率，并且使单体自由基更加稳定。

In the recent years, the company has developed series of the down-stream derivatives of P/O-Chlorotoluene, i.e. 3,000 t/a O- Chlorobenzaldehyde and O-Chlorobenzyl Chloride, 3,000 t/a P- Chlorobenzaldehyde and P-Chlorobenzyl Chloride, 1,500 t/a 2.4- Di chlorotoluene etc. In addition, there is the by-product of 30,000t/a of chlorhydric acid (31-33%). In 2008, the company invested 80 mln yuan, to build the project with 25,000t/a of Maleic Acid by adopting the up-to-date in China technology, thus to improve the product range to a greater extent, and hence to sharpen its competitive edge.

It was found that the fungus 1403 resembles pathogenic F. verticillioides (teleomophy Gibberella moniliforme) in the production of false head or chains and abundant microconidia on the aerial mycelium, but different in the occasional formation of polyphialides with relatively long as well as short monophialides, in its typical coiled hyphae and mycelia fusion.

基于1403在形态学方面具有以下特征：产小型分生孢子的分生孢子梗较长，小型分生孢子呈椭圆形，大型分生孢子线形或略微弯曲，本文将它与有类似形态特征的镰刀菌进行了比较，发现1403与植物病原菌Fusarium verticillioides（有性态为Gibberella moniliforme）表面上很相似，气生菌丝均可产生大量假头状或链状的小型分生孢子，但深入的研究却发现1403与F。
