Efficient synthesis of 8-substituted pyrazolo[1,5-a]-1,3,5-triazines by regioselective acylation
摘要:
An efficient two-step synthesis of 8-acylated pyrazolo[1,5-a]-1,3,5-triazines has been accomplished. The key strategic elements of this novel synthetic approach involve the use of the N-methyl-N-phenylamino activating group, which was easily obtained in high yield by treatment of the pyrazolotriazin-4-one with phosphorus oxychloride and dimethylaniline through high pressure reaction coupled with a regioselective acylation at position 8 followed by the subsequent displacement of the N-methyl-N-phenylamino group upon treatment with various amines.

To identify structurally novel CRF1 receptor antagonists, a series of bicyclic core antagonists, pyrazolo[1,5-a]pyrimidines, triazolo[1,5-a]pyrimidines, imidazo[1,2-a]pyrimidines and pyrazolo[1,5-a][1,3,5]triazines were designed, synthesized and evaluated as CRF1 receptor antagonists. Compounds 2–27 showed binding affinity (IC50 = 4.2–418 nM) and antagonist activity (EC50 = 4.0–889 nM). Compound 5
为了鉴定结构上新颖的CRF1受体拮抗剂,使用了一系列双环核心拮抗剂,吡唑并[1,5-a]嘧啶,三唑并[1,5- a ]嘧啶,咪唑并[1,2- a ]嘧啶和吡唑并[1,5]。 -设计,合成和评价a ] [1,3,5]三嗪作为CRF1受体拮抗剂。化合物2 – 27表现出结合亲和力(IC 50 = 4.2–418 nM)和拮抗剂活性(EC 50 = 4.0–889 nM)。在大鼠的Elevated Plus Maze测试中,发现化合物5显示出口服功效。它们的进一步化学修饰使我们发现了三环核心拮抗剂吡唑并[1,5- a ]吡咯并[3,2- e]嘧啶。介绍了这些化合物的发现过程,以及对结构与活性关系的研究。
