Regioselective reactivity of some 5,7-dimethoxyindoles
摘要:
The reactivity of some 5,7-dimethoxyindoles with respect to electrophiles has been investigated. The favoured sites for reaction are C3 and C4 and regioselectivity can be controlled by the judicious arrangement of electron-withdrawing substituents. Results of formylation, acylation, the Mannich reaction, bromination and nitration are described. (c) 2005 Elsevier Ltd. All rights reserved.
