摘要
3-乙酰吡啶经溴化、环合得4-(3-吡啶基)-1H-咪唑,再经与N-(4-溴丁基)邻苯二甲酰亚胺缩合和肼解得到泰利霉素的重要中间体4-[4-(3-吡啶基)-1H-咪唑基]-1-丁胺,总收率为31%。
4-[4-(3-Pyridinyl)-1H-imidazol-1-yl]-1-butanamine, the side chain of telithromycin, was synthesized from 3-acetylpyridine via bromation, cyclization, condensation with N-(4-bromobutyl) phthalimide and hydrazinolysis with an overall yield of 31%.
