Many rear area cities are located in the south west of china ,which is heavily mountainous and winding rivers .from the ancient times many nationalities have been living here and created unique and glorious civilizations with their qualities of fierceness , valour and vigour ,hardworking and insistency Si Chuan is famous as the land of heaven with favorite weather ,rich production and deeply cultural details , which is equipped with excellent advantages for cultivating arts crafts After the break out of anti Japanese war, Chong Qing became the war -time capital and the vital organs of war-time culture with the westward moving of the national politics ,military .economy and culture, the shifting of colleges of arts and crafts ,artic intellectuals and woodcut organizations.

七七泸沟桥的枪声，打破了战前以上海、北平、广州、杭州等为美术中心的格局，形成了以重庆为轴心的大后方木刻中心和以延安为据点的解放区木刻中心。大后方木刻中心的形成不是偶然的，而有其历史必然性。大后方很多城市地处大西南，这些地方群山逶迤，江河延绵。从远古时期就有众多的民族生息、繁衍在这一区域，并以他们强悍、勇猛、勤劳坚毅的品质和精神，创造了独特而辉煌的文明。

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。
