Cross-coupling reaction on N-(3,5-dibromo-2-pyridyl)piperazines: regioselective synthesis of 3,5-disubstituted pyridylpiperazines
摘要:
Unsymmetrical 3 5-disubstituted pyridylpiperazines were prepared from tribromopyridine in three coupling reactions Key to the success of the syntheses is the palladium-catalyzed regioselective cross-coupling reaction in the 3-position of N-(3 5-dibromo-2-pyridyl)piperazines (C) 2010 Elsevier Ltd All rights reserved
