Then Doripenem came into the market in the July ,2005. We studied the synthesis of Doripemen.Firstly, we synthesized the chemical 2 from the starting material------o-hydroxylphenylacylamine through Reformastky reaction, alkylation, Diekmann reaction, enolization, esterification and etc. Secondly, we synthesized the chemical 3 from L — hydroxylproline through the protection of carboxyl, amidogen and hydroxyl group, reduction by NaBr, SN_2 substitution and Mitsumobu reaction.

我们以水杨酰胺为起始原料，经Reformatsky反应、烷基化、Diekmann环合、烯醇化、酯化等反应合成双环母核2；再从L-羟基脯氨酸出发，经酯化保护羧基、保护氨基、保护羟基、硼氢化还原酯得醇、Sn2取代和Mitsumobu反应等合成巯基侧链3；最后由化合物3经脱保护、水解得硫醇，和化合物2在二异丙基乙基胺的作用下缩合，最后Pd／C催化脱保护，历经16步反应最终得到产物多尼培南。

In pilot test of 150 t/a of synthesizing ethylene glycol tbutyl ether from isobutene and ethylene glycol, reaction temperature, catalyst life, reaction heat draw and affection of LHSV on etherization are investigated.

通过异丁烯与乙二醇合成乙二醇特丁醚 1 50 t/a中间试验，考察了反应温度、液体空速对醚化反应的影响及反应器的撤热情况，考察了催化剂的寿命，提出精制各塔操作参数和产品质量指

Results Six compounds were obtained and their structures were identified as phytol, 7-hydroxycalamenene, daphnetin, and daucosterol from the alcohol extract, D-glycero-D-galacto-heptitol and D-erythro-L-galacto-octitol from the water extract.

结果 从其乙醇提取物中分离得到植物醇、7-羟基去氢白菖烯、瑞香内酯、胡萝卜苷；从其水提取物中分离得到两个多元醇类化合物，分别是D-glycero-d-galacto-heptitol、D-erythro-L-galacto-octitol。

The response to single compound: To both females and males, the compounds that elicit larger responses of adults are benzaldehyde, benzene acetaldehyde, hexanol,β-phenyl ethyl alcohol, benzyl alcohol, cyclohexanol and eugenol. Phytol, 2-methyl-cyclohexanone and β-caryophyllene reveal to have weaker activity.

对单一化合物的反应：两种昆虫，不论是雌蛾还是雄蛾，能引起较强EAG反应的化合物均为苯甲醛、苯乙醛、正己醇、β-苯乙醇、苯甲醇、环己醇和丁香酚，植醇、2-甲基环己烷和β-石竹烯仅能引起微弱的EAG反应。

It was also found that combined addition of α-pinene, pine oil alcohol and camphor, the inhibitors of monoterpenoid pathway, obviously improved taxol production.
