Then we completed the first total synthesis of-Plakoridine A using Eschenmoser couping reaction as akey step. During the synthesis we found the choice of protecting groups and the configuration of the chiralcenter of the substrate play an important role to the key Eschenmoser reaction,so we think our successwould be of guide for synthesizing other polysubstituted pyrrolidines or piperidines.
在论文的第一章中,我们先以易得的对羟基苯乙酸乙酯为原料经多步反应制得了所需的β氨基酸酯,然后利用立体选择性的Aldol缩合反应和内酰胺化反应制得了Plakoridine Alactam,随后,以Eshenmoser缩合反应为关键步骤完成了生物碱-Plakoridine A的首次不对称全合成。

If the fluidity of the injection was bad, the appearance of the product would berough, brittle, and very difficult to satisfy the actual application. In order to improve thefluidity of the melting-body in full filling condition, different types of lubricant function were used in the paper. Though the metallic soap might enhance the fluidity of themelting-body, the dosage was huge, which might cause drops on the mechanics intensityof the product, and cause magnet to be crisp and easy to crack.
为改善在高填充时熔体的流动性,研究了不同润滑剂的作用,金属皂类可以提高熔体的流动性,但用量较大,会导致产品的力学强度的下降,磁体脆而容易开裂,乙撑双硬脂酰胺可以提高熔体的流动性,复合材料的力学强度也较高。
