The total yield of the product was 28%. Bridged imine acetamide was used to produce a new type of antibiotic derivatives from macrolid via removing cladinose sugar from macrolid and joining 6 and 11 position on macrolid ring.

桥红霉素亚胺用于生产新型抗生素类药物——桥红霉素，它是在红霉素内酯环结构上脱掉cladinosesugar，并将红霉素内酯环上6，11位相连，成为全新的红霉素衍生物。

The results of clinical assessment showed that levosimendan was safe and effective which could improve the prognosis of the patients and kept normal blood kinetics. By improving the reported synthetic route, levosimendan was synthesized from acetanilide via eight steps of reaction.

本论文探索了左西孟旦的合成路线，对文献报道的合成工艺进行了合理有效的改进，以乙酰苯胺为原料，最终经Friedel-Crafts反应，羰基α-位溴代，丙二酸二乙酯缩合，水解，脱羧，环合，拆分及重氮化加成等八步反应合成了左西孟旦。

It is broken down via phenylalanine to give acetyl CoA and fumaric acid.

它通过苯丙氨酸降解出乙酰辅酶 A 和反丁烯二酸。

Analogous complexes 3a" and 4a"= CpRu(PPh32, Ar = para-C6H4OMe containing methoxy group at the para-position of gem-diphenyl group were similarly obtained from protonation of the corresponding acetylide complexes via formation of vinylidene intermediate. But only complex 3a'= CpRu(PPh32, Ar2 = fluorenyl is stable in solution, and decomposed to unidentified complex when heated to reflux in THF. Deprotonation of complex 4a in the presence of base gives neutral acetylide complex 6a.

在两个相邻位置的苯基对位位置上接有一甲氧基的衍生物3a"和4a"也可利用类似的质子化反应合成，唯有错合物3a'= CpRu(PPh32， Ar2 = fluorenyl 可以稳定於溶液中，不会进行上述反应，如将其溶於四氢呋喃溶液加热至沸腾则会分解产生无法鉴定的化合物。
