A series of new fluorine-containing analogs of paclitaxel and docetaxel are synthesized using the coupling of (3R,4S)-1-acyl-β-lactams with high enantiomeric purity with properly protected baccatin III, 10-deacetylbaccatin III, and 14β-hydroxy-10-deacetylbaccatin III as the key step (β-Lactam Synthon Method). (3R,4S)-1-Acyl-β-lactams are prepared through efficient chiral ester enolate - imine cyclocondensation
通过将高对映体纯度的(3 R,4 S)-1-酰基-β-内酰胺与受到适当保护的浆果赤霉素III,10-去乙酰基浆果赤霉素III和14β偶联,合成了一系列新的紫杉醇和紫杉萜类似物。-羟基-10-去乙酰基浆果赤霉素Ⅲ为关键步骤(β-内酰胺合成法)。(3 R,4 S)-1-酰基-β-内酰胺是通过有效的手性酯烯酸酯-亚胺环缩合制得的。
