Carboxylate protection for the synthesis of 4,5-disubstituted 1-methylimidazoles
Shapiro,Gomez-Lor
, p. 5524 - 5526 (2007/10/02)
Using the carboxylate function as a readily removed blocking group for the 2-position, a regioselective synthesis of diverse 4,5-disubstituted 1-methylimidazoles has been developed starting from 1-methyltribromoimidazole, 5.
