Pictet-Spengler condensation of aldehydes or alpha-keto-esters with 4-(2-anilinophenyl)-7-azaindole (11) or deazapurine (12) gave high yields of the 3,4-fused cyclic compounds. SAR studies, by varying the substituted benzaldehyde components, lead to the discovery of a series of potent JAK2 kinase inhibitors.
醛或α-酮酯与 4-(2-苯胺基苯基)-7-氮杂吲哚(11)或去氮嘌呤(12)的 Pictet-Spengler 缩合反应以高产率得到了 3,4-稠合环状化合物。通过改变取代苯甲醛成分的 SAR 研究,发现了一系列有效的 JAK2 激酶抑制剂。
