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。
