We synthesized a series of novel 3-phenyl-4-benzylaminopiperidine derivatives that were identified as potent tachykinin NK1 receptor antagonists by structural modification of the 3-benzhydrylpiperidone derivative through high-throughput screening. N-2-[(3R,4S)-4-(2-Methoxy-5-[5-(trifluoromethyl)-1H-tetrazol-1-yl]benzyl}amino)-3-phenyl-1-piperidinyl]-2-oxoethyl}acetamide ((+)-39) was found to be one
我们合成了一系列新颖的3-苯基-4-苄基氨基哌啶衍生物,这些衍生物通过通过高通量筛选对3-苯甲酰基哌啶酮衍生物进行结构修饰而被鉴定为有效的速激肽NK 1受体拮抗剂。N- 2-[(3 R,4 S)-4-(2-甲氧基-5- [5-(三氟甲基)-1] H-四唑-1-基]苄基}氨基)-3-苯基-1 -哌啶基] -2-氧代乙基}乙酰胺((+)- 39)被发现是最有效的速激肽NK 1受体拮抗剂,具有高代谢稳定性。通过动态动力学拆分实现了(+)- 39的高效不对称合成。
