ABT-263, a newly developed Bcl-2 inhibitor, was efficiently synthesized. The key intermediates 4-(4-[2-(4-chlorophenyl)-5,5-dimethylcyclohex-1-enyl]methyl}piperazin-1-yl)benzoic acid and 4-fluoro-3-[(trifluoromethyl)sulfonyl]benzenesulfonamide were efficiently prepared by a three-component Mannich reaction and by nucleophilic fluorination of 1-nitro-2-[(trifluoromethyl)sulfonyl]benzene as the key steps, respectively. Our work may lay a foundation for a new process development of this promising anticancer drug candidate.
新开发的Bcl-2抑制剂ABT-263已高效合成。关键中间体4-(4- [2-(4-氯苯基)-5,5-二甲基环己-1-烯基]甲基}哌嗪-1-基)苯甲酸和4-氟-3-(三氟甲基)磺酰基]苯磺酰胺分别通过三组分Mannich反应和1-硝基-2-(三氟甲基)磺酰基]苯的亲核氟化反应高效制备。我们的工作可能为此有前途的抗癌候选药物的新工艺开发奠定了基础。
