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。

Second, using DBU as the base for enolization of propargylic esters of unsaturated acids 18e-k, we developed a tandem Ireland-Claisen rearrangement /isomerization reactions. It has been shown that the reaction sequence affords triene molecules 42a-b and 43a-b in moderated to high yields. Interestingly, with allyl hexa-3,5-dienoates 18i-j as the substrate, the rearranged products underwent further aromatization to give uniquely substituted benzyl acids 44a-b.

其次,以含有活泼质子的烯酸炔丙酯18e-k为底物,在DBU为烯醇化碱、TMSCl为硅试剂的条件下,底物18e-h发生了Ireland-Claisen重排/异构化串联反应,得到完全共轭的三烯类化合物42a-b及43a-b;而以己二烯酸炔丙基酯18i-j为底物时,重排/异构化后的产物进一步发生电环化等反应最终得到芳构化产物——取代苯甲酸类化合物44a-b。

We researched on the prepartion of pivotal intermediate 2 and 3 for 1 P-methyl carbapenem antibiotics from intermediate 1, which is subjected to Reformastky reaction, N-alkylation, Dieckmann-type cyclisation, enolization, ester condensation etc. in sequence. The synthesis route of document is optimized by us.

我们研究了1β-甲基碳青霉烯类重要中间体的合成,从中间体1出发经Reformastky反应、水解反应合成出中间体2;经Reformastky反应、烷基化、Dieckmann环合、烯醇化、酯化合成出中间体3,并对其中各步反应作了优化和探索。

The second synthetic strategy commenced from butane-1,4-diol 50, which underwent monobenzylation, Swern oxidation, enolization followed by acetylation and debenzylation to yield an intermediate 46 in an overall yield of 54% in a 4-step procedure.

第二条路线从1,4-丁二醇50开始,这个化合物经过单苄基化、Swern氧化、烯醇化随后乙酰化和脱苄基化共4步反应得到中间体46,总产率54%。

We studied DBU-mediated Ireland-Claisen rearrangement. Using DBU as the base for enolization of allylic esters of unsaturated acids 9-16, we found a novel DBU-mediated tandem Ireland-Claisen rearrangement /isomerization reactions and established a consecutive Ireland-Claisen rearrangement /Cope rearrangement.

利用DBU作为烯醇化碱,对含有活泼质子的烯酸烯丙酯类化合物9-16的Ireland-Claisen重排进行了系统的研究,创建了一条新颖的DBU-促进的Ireland-Claisen重排/异构化串联反应及Ireland-Claisen重排/Cope重排的串联反应路线。
