A novel chemotype of kinase inhibitors: Discovery of 3,4-ring fused 7-azaindoles and deazapurines as potent JAK2 inhibitors
摘要:
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. (C) 2009 Elsevier Ltd. All rights reserved.

A new strategy has been introduced to develop a catalyticasymmetric Pictet–Spengler-type reaction by replacing the aldehyde with an imine. A range of 4-(2-aminoaryl)indoles smoothly undergo the chiral phosphoric acid catalyzed asymmetric Pictet–Spengler-type reaction with imines at room temperature to give structurally diverse indolo[3,4-cd][1]benzazepines in good to excellent yields and ee.

An efficient and versatile method for the synthesis of indole-based polycyclic indolo-benzazepine and its derivatives through water-acceleratedcationic π-cyclisation is described. The strategy involves condensation of arylamine moieties linked to C-4 in indole/azaindole systems with arylaldehydes in water containing catalytic amount of Bronsted acids. The C-C bond formation in water is complete within
