摘要:In this study, we report a new strategy for the synthesis of 2,4-disubstituted pyrroles using a stepwise iododesilylation and palladium-catalysed Suzuki coupling reaction of 2,4-bis(trimethylsilyl)-1-t-Boc-1H-pyrrole (2). The regioselective iodo-desilylation followed by the Suzuki coupling reaction with concomitant Boc deprotection are critical aspects of the new synthesis method. (C) 2016 Elsevier Ltd.
