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 the presence of NaH and in DMF, the acyclic crown ethers 1a and 1b were synthesized by the reaction of di-or triethyleneglycol ditosylate and o-methoxymethoxybenzyl alcohol, which was obtained from salicylaldehyde via the protection of the hydroxyl group with chloromethyl methyl ether followed by the reduction of the formyl group with NaBH4. The hydrolysis of 1a and 1b with dilute hydrochloric acid provided the diphenolic type acyclic crown ethers 2a and 2b respectively in good yield.
将水杨醛与碱和氯甲基甲基醚反应,再经过NaBH4还原,即制得邻苯甲醇,然后将其在DMF中与NaH和二甘醇二对甲苯磺酸酯反应,得开链冠醚1a和1b.1a和1b经稀酸水解,即脱保护而分别生成新的酚型开链冠醚2a和2b。

In its natural form as willow bark and leaves, this remarkable remedy dates back to Hippocrates. In 1829 the chemical in the willow tree that can relieve pain and fever was discovered to be salicin. By 1899 the Bayer Company in Germany had marketed a variant, acetylsalicylic acid, under the name of aspirin.
柳树皮和柳树叶是其天然形式,这种疗效显著的药物可以回溯到希波克拉底时代。1829年,人们发现柳树中能止痛退烧的化学物质为水杨醇葡萄糖甙。1899年,德国拜耳公司上市了一种变种商品,命名为阿司匹林。
