An efficient one-pot synthesis of 1,2,4-triazoloquinoxalines
摘要:
A transition metal-free tandem process for the synthesis of 1,2,4-triazoloquinoxalines was described. The construction of this tricyclic system went through a one-pot condensation/nucleophilic aromatic substitution approach. This methodology applied to a broad range of substrates, which included 2-halogenated or 2-nitro aryl aldehydes and ketones. (C) 2014 Elsevier Ltd. All rights reserved.
