Therelationship of the amount of catalyst and the ee% of product was seen to be negative nonlin-ear. Catalyst 3 was used in the enantioselective addition of diethylzinc to aromatic aldehydesand gave good results. The configuration of products was determined by the configuration ofthe catalysts' chiral carbon linked with hydroxy group. Using β- amino alcohols bearing only one chiral center as catalysts for the enantiose-lective addition were studied. D-N, N-dialkyl-2-amino butanol gave poor catalytic effect be-cause of their structure. The configuration of the product is the same as the catalyst. Anotherkind of β- amino alcohols - phenylglycine derivatives and valine derivatives have chiralcenter on the carbon linked with amino group. Catalyzed by-phenylglycine derivatives 6,7, 9, 10, the reactions gave satisfied results. The optical yields exceeded 80%.

在探讨了含有两个手性中心的β-氨基醇之后，选择了只有一个手性中心的β-氨基醇，一是手性中心为连羟基的手性碳原子：D-N，N-二烷基-2-氨基丁醇；二是手性中心为连氨基的手性碳原子：D-苯基甘氨酸衍生物和L-缬氨酸衍生物。D-2-氨基丁醇的催化效果不太好，这与其结构的空间位阻较小有关系，反应产物与连羟基手性碳构型一致；由苯基甘氨酸和缬氨酸出发合成五种β-氨基醇6-10，研究了不同ee％的-6作用下的二乙基锌-苯甲醛加成反应，发现该催化剂具有不对称放大效应；-7，9，lO的催化效果也比较令人满意，光学产率80％以上，所得产物构型与催化剂构型一致。

With the diminishing marginal utility, the point of tangency may run to the area far to the central city. Through the statistics and analysis, we find out that there are several characteristics in the central city tourism market:(1) The city tourists tour at weekends and gold weeks, and they want to buy such tourism products as """" safe, convenience, short range and cheap"""".(2) They tour by car or by themselves not go with tour team,(3) and stay out for zero to two nights.(4) There have more female than male tourists.(5) They like to select scene or leisure spots, but holiday tourism becomes more and more ppopular.(6)The segment markets of silver hairs, teachers and students have great perchasing power.

本文重点对中心城市居民出游市场进行了统计分析，通过分析发现中心城市出游市场总体表现出以下特点：(1)城市居民外出旅游时间除黄金周以外，主要集中在周末，其时间约束型的旅游产品需求以"安、近、短、廉"为特征的旅游产品为主；(2)出游方式以自驾车和自主安排为主，团队游客的比例在逐步下降；(3)出游逗留时间以在外逗留0—2夜为主；(4)城市居民出游人群中女性比例高于男性；(5)出游目的以近距离观光、休闲为主，但度假市场正在蓬勃发展，现在中心城市周边新兴的"农家乐"就是度假旅游的雏形和低级形式；(6)中心城市银发市场和教师、学生市场是两个原来被忽视却孕育着巨大潜力的细分市场。

The synthesis of the pentacyclic skeleton of Et-743 and the construction of the five chiral centers thereof.1. The core pentacyclic skeleton of phthalascidin was constructed with L-dopa as the starting material via thirteen steps. First, two basic synthons, the C-1 functionalized tetrahydroisoquinoline compounds 8 and N-protected Z-dopa derivative 9, were prepared from L-dopa. They were coupled via amide bond to form the dipeptide compounds 10, which were the first key intermediates. Then the primary hydroxyl groups were transformed into the corresponding amino aldehydes 11 via Swern oxidation. Followed by the intramolecular Pictet-Spengler cyclization, the pentacyclic compounds 12 were synthesized.

五环骨架的构建及五个正确手性中心的确立：1.1我们以L-多巴为起始原料，经过多步官能团保护和转化合成了基本结构单元8然后和苯丙氨酸衍生物9，通过缩合反应生成酰胺中间体10，经Swern氧化得到醛化合物11，然后再次利用分子内改良的Pictet-Spengler反应一步构建c，d两环，得到五环骨架化合物12，最后，实现了21-位羰基向氰基的转化，得到了C-1位官能化的化合物14，化合物14不但具有和Et-743一致的五环骨架，而且分子中五个手性中心立体构型也与其完全相同：其中，3，位和13，位的手性中心由原料L-多巴带入，而1，位，11，位和21，位手性中心则通过不对称诱导而确立。
