Abstract
The reaction of N-alkoxycarbonyl-O-tosylhydroxylamines with indol-2-ones in situ generated from 3-halooxindoles has been developed for divergently accessing 4-aminoquinolin-2-ones and N-Cbz-N’-arylureas in good to excellent yields.

[PMID: 16678414 DOI: 10.1016/j.bmcl.2006.04.043] [Citation(s) in RCA: 12] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/29/2006] [Revised: 04/14/2006] [Accepted: 04/14/2006] [Indexed: 10/24/2022]
Abstract
The 3-benzimidazol-2-yl-1H-indazole scaffold was developed as an alternate scaffold for our receptor tyrosine kinase (RTK) inhibitor program. In exploring the SAR of this series, it was discovered that a subset of these compounds potently inhibit the enzyme c-ABL. The SAR of these compounds is described.
